Based on Ni powder, there is the Refining Mechanisms completely different with Co powder.
Mainly WC grain is refined, by stringent technology controlling and process, reduces hole by adding alloying element in the prior art
Improve the performance of WC-Ni hard alloy with the methods of defect.The WC-Ni mixtures prepared using conventional method are in vacuum-sintering
Under the conditions of often there is " nickel pond " and hole." nickel pond " and hole can seriously affect the comprehensive performance of alloy, such as intensity, wear-resisting
Property, corrosion resistance etc..
Silica dioxide gel has heat-insulating property is good, nanostructure is controllable, corrosion resistance and good, biocompatibility are excellent etc.
Feature, but SiO2Gel has that adhesion strength is low if being directly coated on alloy surface, it is therefore desirable to introduce film forming agent
It is modified.Polyvinyl alcohol is a kind of nontoxic, transparent polyhydroxy based high-polymer, when as a kind of organic coupling agent and SiO2It is molten
Glue has good combination effect.On the one hand, SiO can be made2Dissolved adhesiveness increase and it is good with the binding performance of Ti-Ni matrixes,
To effectively improve the bond strength of coating；On the other hand, PVA solvents can also effectively fill SiO2Colloidal sol is forming gel mistake
The hole gap formed in journey, improves the performances such as the consistency, wearability, hardness of coating.
