Fall into, adopt new technology, new method, new formula prepare there is high rigidity, high-wearing feature, highly corrosion resistant, heterogeneous microstructure is equal
Even, the excellent material of comprehensive mechanical property becomes the demand that people are urgent.
Summary of the invention
Poor in order to solve conventional coatings wearability, the problems such as hardness is relatively low, the present invention provides a kind of Ni60A-WC-CaF2
Nano coating and preparation method thereof.
The technical problem to be solved realizes by the following technical solutions:
A kind of Ni60A-WC-CaF2Nano coating, the mass fraction of its component and each component is that Ni60A accounts for 12-37 part, WC
Account for 52-81 part, CaF2Account for 1-10 part, trace element accounts for 1 part.
Described trace element is Cu, B, Fe, and the proportioning of Cu, B, Fe is 1:0.5:1.
A kind of Ni60A-WC-CaF2The preparation method of nano coating, comprises the following steps:
(1) dry type comminuting method is used to prepare Ni60A-WC-CaF2Nanosphere；
(2) nanosphere prepared in step (1) use surfactant Protection Code mixing Cu, B, Fe prepare nano powder
End；
(3) laser melting coating spraying coating process is used to prepare on iron-base workpiece surface in the mixture prepared in step (2)
Ni60A-WC-CaF2Nano coating.
The invention has the beneficial effects as follows: the present invention solves the problem that existing coating abrasion performance is poor, corrosion resistance is relatively low,
Improve the microstructure of material surface coating, structure, make coating hardness improve 65%, elastic modelling quantity improve 4%～
9%, thus the overall anti-wear performance improving material surface.
