[Industrial Application Field] This invention relates to a method for surface treatment of titanium or titanium alloy. [Prior Art] Traditionally, titanium or titanium alloys, like aluminum or aluminum alloys, are chemically very active and easily react with various chemicals, but like stainless copper, they are very passive. It is known to have excellent corrosion resistance and chemical resistance against a variety of strongly oxidizing acids, alkalis, and other chemicals. .
Further, titanium or a titanium alloy has high specific strength (ratio of strength to density), and has appropriate toughness, heat resistance, thermal stability, and workability. Therefore, it has come to occupy a major position as a chemical plant material and aerospace aircraft material. However, titanium or titanium alloys have poor wear resistance, seizure resistance, rosion resistance, heat radiation properties, etc., and therefore their uses are limited. In other words, titanium or titanium alloys are used mainly for their heat resistance and high specific strength (ratio of strength to density) to prevent wear when used in primary structural members such as solar cell frames of space equipment. However, it had the disadvantage that it could not be put to practical use because of the considerable radiant heat caused by direct sunlight. In order to improve this drawback, a method is known in which the surface of a base material made of titanium or a titanium alloy is coated with a film that has high abrasion resistance and is for selective absorption of solar heat. Examples of such methods include (a) various black plating methods using electrolytic plating, (b) dry plating methods such as sputtering and ion plating, (c) chemical conversion coating methods, and (d) painting. The method according to
(e) An anodic oxide film treatment method may be mentioned. [Problems to be Solved by the Invention] The conventional surface treatment method for titanium or titanium alloy as described above has the following problems. That is, according to method (a) above, black chrome plating or black nickel plating is performed through processing steps such as steam degreasing, blasting, etching, and activation. When it comes into contact with air or water during the processing step, a thin oxide film is formed and becomes passive, resulting in insufficient adhesion of the plating film. Efforts are generally made to improve this adhesion through heat treatment, but this heat treatment requires a relatively high temperature of 450°C or higher.
Requires expensive equipment. In the method (a) above, aluminum, nickel,
A film of chromium, etc. is formed using equipment such as sputtering or ion plating, and then a black chemical conversion film treatment is performed to obtain the desired film, but the equipment is expensive and the adhesion of the film is not stable. I can't get what I wanted. The above method (c) has been very well researched as a method for treating the surface of base materials such as aluminum, aluminum alloy, steel, stainless steel, etc.
There are few reports on titanium or titanium alloys, and the inventor's studies have not yielded good properties. In the method (d) above, black or white paint is directly sprayed onto the surface of the base material made of titanium or titanium alloy, but the resulting paint film cannot be used practically in areas where significant wear occurs. Can not. In the method (e) above, titanium or a titanium alloy is used as an anode and electrolyzed in an aqueous solution containing sulfuric acid, but the resulting film is blue and cannot be used for practical use because the desired color cannot be obtained. I can't. There was a problem. This invention was made to solve the above-mentioned problems, and its purpose is to provide excellent abrasion resistance to any part of the base material surface and to provide excellent sunlight resistance by a relatively simple method. It is an object of the present invention to provide a method for applying a treated layer having absorbent properties. [Means for solving the problems] As a result of extensive studies, the method for surface treatment of titanium or titanium alloy according to the present invention has been developed.
It has been found that the above object can be achieved by coating the surface of a substrate made of titanium or a titanium alloy with a layer of molybdenum disulfide, and the present invention has been completed. That is, in the surface treatment method for titanium or titanium alloy of the present invention, the surface of a base material made of titanium or titanium alloy is finished to a desired surface texture by a mechanical method, and then treated with trisodium phosphate or potassium fluoride. The method is characterized in that it is coated with a molybdenum disulfide (MoS 2 ) film after being chemically treated in a mixed aqueous solution consisting of hydrogen fluoride. In the following, the invention will be explained in more detail. In the surface treatment method of the present invention, first, the surface of a base material made of titanium or a titanium alloy is finished to a desired surface roughness by a mechanical method. As such a mechanical method, for example, a dry honing device may be used, or liquid honing may be used. In such a treatment, for example, 300 to 400 meshes of glass beads are sprayed onto any part of the surface of the substrate at an air pressure of 2 kg/cm 2 to 5 kg/cm 2 . When spraying onto the surface of the base material, it is preferable to spray evenly onto the required areas. The surface treatment method of the present invention then remained on the surface of the substrate made of titanium or titanium alloy.
Trisodium phosphate, potassium fluoride,
Chemical treatment is carried out in a mixed aqueous solution consisting of hydrogen fluoride. Such chemical treatment may be performed at a temperature of 70°C to 90°C, for example.
It lasts about 5 to 15 minutes. It is preferable that the treatment temperature and treatment time are appropriately selected depending on the condition of the surface of the substrate. In the surface treatment of the present invention, a molybdenum disulfide (MoS 2 )-based coating treatment is then performed to impart wear resistance to the surface of the base material made of titanium or a titanium alloy and to provide a selective sunlight absorption film. Such molybdenum disulfide (MoS 2 )-based coating treatment uses, for example, a special resin in which ultrafine particles of molybdenum disulfide are dispersed, and the surface of the base material made of titanium or titanium alloy is coated with a special spray gun. It is sprayed at an air pressure of 1 to 2 kg/cm 2 . Drying after spraying is carried out, for example, at a temperature of 200° C. for about one hour. [Function] In this invention, in order to finish the surface of a base material made of titanium or a titanium alloy to a required surface roughness by a mechanical method, a molybdenum disulfide (MoS 2 )-based coating is applied to a base material made of titanium or a titanium alloy. Adhesion to the material surface is significantly improved. Further, in this invention, trisodium phosphate,
When the surface of a substrate made of titanium or titanium alloy is mechanically finished to the required surface roughness by chemical treatment in a mixed aqueous solution consisting of potassium fluoride and hydrogen fluoride, foreign matter adhering to the surface can be removed. Remove. Next, in this invention, by coating with a molybdenum disulfide (MoS 2 )-based film, a treated layer having wear resistance is imparted to the surface of a base material made of titanium or a titanium alloy, and it also has excellent sunlight absorption properties. A treatment layer having the following properties can be applied. [Example] The present invention will be described in more detail below with reference to Examples. Example A base material made of pure titanium and having a diameter of 20 mm and a thickness of 10 mm was treated according to the following steps. (1) Triclean degreasing Immersed at a temperature of 80 to 90°C for 90 seconds. (2) Dry honing #300 glass beads were sprayed at an air pressure of 3 kg/cm 2 . (3) Chemical treatment Trisodium phosphate 50g/, potassium fluoride
It was immersed in a mixed aqueous solution containing 20 g/hydrogen fluoride and 10 g/hydrogen fluoride at a temperature of 75° C. for 10 minutes. (4) Water washing: 1 to 2 minutes under running water. (5) Hot water washing: Immersed at a temperature of 80 to 100°C for 60 seconds. (6) Drying was carried out at a temperature of 50°C for 30 minutes. (7) Molybdenum disulfide (MoS 2 )-based coating treatment Coated with a spray gun at an air pressure of 1.5 Kg/cm 2 . (8) Natural drying was carried out at room temperature for 30 minutes. (9) Baking was carried out at a temperature of 200°C for 60 minutes. The solar characteristics (ratio of solar absorption rate to infrared emissivity) and temperature rise (surface temperature) using a solar simulator were measured for the treated base materials and untreated materials obtained through the above treatments. . The test results are shown in the table.
