WJ82228 硬化镀膜可延长工具的寿命——《Metal Progress》,1981,Uol119,№7,44～46(英文) 在化学气相镀膜中所有化学反应的最初产物是气体,而最终的产物之一是固体。如果仅应是在气相状态下进行的,固态沉积物是以粉末状态存在的。反应仅只在固、气相的交界面进行并在工件上产生一致密的固体镀膜层。在化学气相镀膜工艺中有4种不同的工业镀膜材料——碳化钛、氮化钛、碳化铬和氧化铝。氯化
WJ82228 Hardened Coating Extends Tool Life - Metal Progress, 1981, Ulll9, № 7, 44-46 The initial product of all chemical reactions in chemical vapor deposition is gas and one of the final products is a solid . If only in the gas phase, the solid deposits are in the form of a powder. The reaction takes place only at the interface between the solid and the gas phase and produces a dense solid coating on the workpiece. In the chemical vapor deposition process there are 4 different industrial coating materials - titanium carbide, titanium nitride, chromium carbide and aluminum oxide. Chlorinated
