摘要:
Cutting tool has a substrate and a multilayer coating deposited by PVD. The coating comprises a base layer of one or more identical or different layers of a nitride or carbonitride which contains at least aluminium (Al) and a chromium-containing, oxidic functional layer. Attachment of the chromium-containing functional layer is improved by an intermediate layer of one or more oxides or oxide nitrates of the metals Al, Cr, Si, and/or Zr provided between the base layer and the functional layer. The intermediate layer has a cubic structure and the chromium-containing functional layer is selected from chromium oxide (Cr2O3), chromium oxynitride, aluminium-chromium oxide (AlCr)2O3, aluminium-chromium oxynitride or a mixed oxide or mixed oxynitride of aluminium, chromium and further metals of (AlCrMe1, Men)2 oxide or (AlCrMe1, Men)2 oxynitride, where Me . . . Men means one or more further metals, selected from Hf, Y, Zr and Ru, and wherein the functional layer has a rhombohedral structure.
摘要(中):
切割工具具有通过PVD沉积的基底和多层涂层。 该涂层包含至少包含铝(Al)和含铬氧化功能层的氮化物或碳氮化物的一个或多个相同或不同层的基层。 通过设置在基层和功能层之间的金属Al,Cr,Si和/或Zr的一种或多种氧化物或氧化物硝酸盐的中间层来改善含铬功能层的附着。 中间层具有立方结构,含铬功能层选自氧化铬(Cr 2 O 3),氮氧化铬,铝 - 氧化铬(AlCr)2 O 3,铝 - 氮氧化铬或铝,铬的混合氧化物或混合氮氧化物 和(AlCrMe1,Men)2氧化物或(AlCrMe1,Men)2氮氧化物的其他金属,其中Me。 。 。 男士是指选自Hf,Y,Zr和Ru中的一种或多种其它金属,其中功能层具有菱形结构。
