The research results show that, from the viewpoint of second phase morphologies, there exist quite differences between the grain - type materials ( such as wc / bcu brazing deposit material, wrs1000 and 1zt tungsten carbide strengthening overlaying material, as well as the wear - resistant material of polymer adhesive coating etc. ), and the aggregation - type as well as dispersion - type ones ( such as zg35simn, wrd - 1 and khc - k2 depositing material ) in the wear - resistance and sand slurry abrasion mechanism. the sand slurry abrasion mechanisms are brought forward, of new wear - resistant materials with the features of grain - type second phase morphologies
