查询词典 grains

A new cermet sinter with through micro-porous structure was developed by vacuum liquid phase sintering method, in which Al2O3-Ni-Cr-Mo-Si-Fe powder was used as the basic material, TiH2 and CaCO3 were used as the composite pore-forming materials and hominess grains was used as dispersal particles. The cermet sinter was then infiltrated with Ag-Cu-Pb-Sn at vacuum and formed a new high temperature self-lubricating material.
