WC particle reinforced high chromium cast iron (Cr20) matrix compound roller has been prepared successfully by means of centrifugally cast spraying.

WC particle reinforced cast iron matrix composites are manufactured by the vacuum infiltration technique.

This thesis fabricated successfully a WC particle reinforced iron matrix composite using a vacuum infiltration process for severely erosion and application in the slurry pump.

Using presetting methods of coated preform,SiC particle reinforced steel matrix surface composites were prepared by vacuum evaporative pattern casting(V-EPC)infiltration.

Progress in research of SiC particle reinforced Al-based matrix composites is reviewed;material selection,manufacturing process and mechanical properties were discussed.

The method for measuring the porosity of stirring cast made SiC particle reinforced aluminum matrix composites is introduced in this paper.

In order to compare the tribological properties of two aluminum matrix composites reinforced by different content of B4C particles,the pin samples were prepared with them and friction and wear tests of pin-on-steel disc were carried out on a multifunctional tribometer.

The result revealed that SiC particles as solid solutions in casting surface are combined together with the alloyed matrix or steel substrate and the particle shapes are kept intact and uniformly distributed,thus forming metallurgical bonding between wear-resistant coating and matrix.

Current status of development and application in SiCp/Al composites;
