摘要: The invention belongs to the field of machining cutting tools, and particularly relates a ZrMoCN gradient composite coating tool preparing method thereof. is prepared through with an unbalanced magnetron sputtering arc plating method. sequentially comprises base body, Ti transition layer, ZrMoC layer nitrogen content gradually changing in manner front interior exterior. In ultrahard carbohydrates nitrogenous compound coating, due fact that Zr element Mo are added at same time, which structure component changes manner, comprehensive using performance can be improved. has very high hardness tenacity good anti-oxidization friction abrasion characters, expanding cracks prevented. process, bonding between workpiece dry process reduced tool, force temperature by 30% or above, improved 45% service life prolonged 40% durability above.
