ィングされることが多い。2. Related Art and Problems Thereof Fluororesins have excellent wear resistance and lubricity, and are often used as coating materials for various mechanical members, particularly sliding members such as pistons and cylinders. Since the fluororesin itself is soft, it is often coated on a steel or aluminum base material when applied to a sliding member subjected to a large load and severe wear.

プライマーで処理する必要がある。By the way, fluororesins have a property that they do not easily adhere to other materials due to their excellent non-adhesiveness. Therefore, to coat it on other materials, it is necessary to roughen the surface of the substrate to be coated or to treat this surface with a primer.

いう欠点がある。Examples of the method for roughening the substrate include a mechanical polishing method such as a wire brushing method and a sand blast method, and a chemical or electrical etching method. However, in the former method, sufficient adhesion between the substrate and the coating film cannot be obtained,
Further, the latter method has a problem that the material of the substrate is limited due to the etching selectivity of the substrate. On the other hand, in the case of the primer treatment, there is a disadvantage that the thickness of the coating film is inevitably increased, and the dimensional accuracy of the sliding member is reduced.

Then, a rough surface having a roughness of 1 to 10 μm (Rmax) is formed, and then an etching resist is printed in a grid pattern on the surface to be coated with a resin, and a mask portion of the resist and a large number of squares or rectangles are formed. A non-mask portion is formed, then the non-mask portion is etched, and a large number of cross-sectional groove shapes having a tapered inner peripheral wall gradually tapering from the bottom to the opening and having a depth of 20 to 50 μm. In addition to forming the resin-embedded concave portion, the inner surface of the concave portion is roughened.

When electrical etching is performed, DC electrolysis, AC electrolysis or AC / DC superposition electrolysis is performed in an electrolytic solution containing an alkali. DC electrolytic etching is particularly preferred in that it does not damage the print resist. As a result of this etching, the non-mask portion is formed as a concave portion for anchoring the resin.

る。Effect of the Invention The undercoating method in resin coating of a metal sliding member according to the present invention is to roughen the surface of the metal sliding member to be coated with the resin before resist printing, and to coat the entire surface of the metal sliding member with the resin.
A rough surface having a roughness of 1 to 10 μm (Rmax) is formed, and then an etching resist is printed in a grid pattern on the surface to be coated with a resin, and a mask portion made of the resist and a number of square or rectangular non-masks are formed. Forming a portion, then etching the non-mask portion, having a tapered inner peripheral wall gradually tapering from the bottom to the opening and having a cross-sectional groove-shaped multiple resin having a depth of 20 to 50 μm. According to the present invention, the surface on which the resist is to be printed is roughened in advance so that the embedded recess is formed and the inner surface of the recess is further roughened. Even if the mask part is not etched in the next step,
Great adhesion to the resin layer covering this portion can be exhibited. Therefore, it is possible to effectively solve the problem when the adhesion is poor in the mask portion.

させることができる。In addition, a dense and constant roughened grid-like pattern can be formed extremely stably on the surface of the metal sliding member by etching, and the etching concave portions (pores) have a substantially constant size. Many fine irregularities are also formed on the inner surface of the concave portion. Accordingly, by coating the sliding member having such a rough surface with resin, an excellent resin anchoring effect is exerted on the concave portion of the rough surface, and the adhesion of the resin coating layer to the sliding member is greatly improved. be able to.

きるものである。In particular, due to the synergistic effect of the roughening before the resist printing on the surface of the metal sliding member and the roughening to the inner surface of the concave portion by the etching process, the adhesion of the resin coating layer to the sliding member is achieved. Sex can be further increased.

ことができる。In addition, the rough surface pattern can always be the same without being affected by the material of the sliding member, the composition of the etching solution, the etching conditions, etc., so that the resin coating layer adheres to the sliding member. It is possible to form a resin coating layer of a constant quality having a stable property and excellent abrasion resistance.

服することができる。Furthermore, since the heights of the convex portions of the base material provided by the formation of the concave portions for resin anchoring are all uniform, the softness, which is a drawback of the fluororesin, should be overcome as much as possible by the convex portions of the hard base material. Can be.
