高速钢微径立铣刀的Ni-Mo-P化学镀工艺

基于化学镀Ni-Mo-P具有高硬度、表面光洁、可在复杂型面上获得均匀镀层等优点,将其应用于高速钢微径立铣刀上,并通过铣削试验对镀层性能进行分析。结果表明:Ni-Mo-P三元合金镀层对于提高高速钢微径立铣刀的表面硬度、增强局部刚性具有一定效果;镀层结合力是影响Ni-Mo-P化学镀在高速钢微径刀具上推广应用的关键制约因素。

Ni-Mo-P Electroless Deposition on High Speed Steel Micro End Mill

Base on the advantages of Ni-Mo-P electroless deposition,such as high hardness,smooth surface,uniform coating for complex parts etc,the Ni-Mo-P electroless deposition is used to HSS micro end mill.Finally the coating per-formance is tested though actual end milling operation.The result shows that the Ni-Mo-P alloy coating can evidently im-prove surface hardness and local rigidity of micro end mill,but the coating binding force is still the key factor of influencing the application of Ni-Mo-P electroless deposition on HSS micro end mill.
