当前应用气相沉积改善高速钢刀具的切削性能正越来越受到国内外有关方面的高度重视。自七十年代以来,用物理沉积的方法在钢质上、模具上涂复TiC、TiN等超硬涂层的新工艺得到了迅速发展,我国七十年代中期开始研制。涂层的工艺方法多种(ARE法、HCD法……)。我们的刀具是在唐山机械研究所 The current application of vapor deposition to improve high-speed steel cutting tool cutting performance is more and more concerned by domestic and foreign parties attach great importance. Since the seventies, with the method of physical deposition on the steel, the mold has been coated with TiC, TiN and other superhard coatings has been the rapid development of new technology, China began in the mid seventies development. Coating a variety of methods (ARE method, HCD method ...). Our knives are at Tangshan Machinery Research Institute
