However, Mg is one of the few metallic elements which may exhibit good tribological compatibility with iron and steel and as such is a possible candidate to replace lead in sliding bearing materials.
Introduction For almost a century, Cu-1%Sn-25% Pb-bronzes have been used in journal bearings, with the CuSn matrix providing the mechanical strength of the alloy and Pb promoting tribological compatibility.
Al-Sn alloys for journal bearings are produced by thin slab casting, followed by cold rolling and roll-bonding onto the steel backing.

At present, the approach of obtained the ceramic drawing die materials are mainly thermal spraying, CVD, etc.
The project obtained ceramic drawing die materials by laser alloying is a green manufacturing, while it formed metallurgical bonding with the substrate which has high combined strength, and the development prospects is broad.
The project not only has some innovative research but also have economic, social as well as academic significance; This project combined the fields of machinery, materials and laser technology which can promote the integration of various disciplines and development, so it has important applications and academic value.

To manufacture composite materials with enhanced properties, different kinds of the literature suggested implementing coating materials on either fibers or nano-fillers.
The material composition of the composite materials affects heavily the mechanical properties and the associated natural frequencies of the composite structure.
