The establishment of the physical model Related hypothesis. 1) Material continuous and for isotropic; 2) the laser absorptive of materials surface not changing with temperature; 3) Ignore the molten pool flow; 4) Ignore material vaporization; 5) Because of laser heating time is very short, do not consider molten pool liquid flow on temperature field influence.

High-purity alumina has excellent performance and wide application in high-tech industries and areas of modern materials, so industrialized, low-cost, non-polluting and sustainable development preparation process has become one of the priorities of present high-purity alumina powder research.
The demand and application in high-precision and wear-resistant materials such as the catalyst carrier, the carrier coating, components material of mechanical products, fluorescent translucent coatings and other emerging fluorescent decorative materials, luminescent diode substrate materials, HPS transparent alumina tube, anti-scratch disk of scanner, special optical instrument windows, metal-ceramic additives in lubricating oil, as well as artificial crystals (artificial sapphire and ruby of laser materials) are more and more concerned [2] - [9].

These materials combine a soft metallic matrix with hard ceramic particles that withstand wear [1].
The carbides produced by this method showed an improvement of several properties that materials can be compared to materials obtained by conventional processes.

Composite materials have superior properties than those of the individual components when used alone depending on the type of materials being combined [3].
The concept behind composite materials is the combination of two or more materials in creating a new engineered material [4].
The classification of composite materials is based on the binder material, which binds or holds the filler materials, usually a polymer matrix, and the filler material, usually the fibers, sheets, fragments, particles, or whiskers of natural or synthetic material [1].
