LOW FRICTION COATING FOR MELT BLOWN DIE AND PREPARATION METHOD FOR COATING
The present disclosure belongs to the technical field of melt blown dies, and provides a preparation method for a low friction coating for a melt blown die. In the present disclosure, pretreatment, activation treatment, chemical deposition, and calcination are conducted on a surface of the melt blown die in sequence to deposit an Ni—P—Re coating on the surface of the melt blown die, thereby reducing the friction coefficient of the melt blown die. In the present disclosure, surface smoothness and hardness of the coating are improved by limiting the composition and ratio of a deposition solution used for the chemical deposition. The results of examples show that the low friction coating for a melt blown die prepared by the preparation method provided by the present disclosure has a thickness of 3.2 μm, hardness of 820 HV, roughness Ra of 0.02 μm, and a friction coefficient of 0.35 under non-lubricating conditions.
