この目的は、
・第1の基材から製造されて外面を有するコア要素と、
・コア要素の外面の少なくとも一部を覆う少なくとも70%の濃度の耐食性材料を含むコーティング層と、
コア要素とコーティング層との間に合金域が存在し、該合金域が、前記耐食性材料の濃度がコーティング層内の濃度の90%である部分から前記耐食性材料の濃度がコーティング層内の濃度の10%である部分まで0.1マイクロメートル〜10マイクロメートルの厚みを有し、物体の表面が機械的に加工されることにより、コア要素の表面、合金域及びコーティング層が当該加工により影響を受けて成る物体
により達成される。
例えば、コア要素(1)がオーステナイトステンレス鋼(AISI304又は316)で構成され、コーティングを950℃で堆積した場合、非多孔質の良好に接着したコーティングが得られることが判明し、この場合、タンタルとステンレス鋼エレメントとの相互拡散部である合金域は、顕微鏡写真の目視観測により約1.5μmであった。
最大0.5%のCを含む炭素鋼基材を625〜900℃でコーティングすることにより、ステンレス鋼上のコーティングと同様のコーティングが得られるが、この場合良好な接着性がより容易に得られる。875℃で195分間堆積したコーティングでは、顕微鏡写真で視覚的に観察される1〜1.5μmの拡散域又は合金域を示した。
6A、6B 突出部。
