Abstract

In recent years, functionally gradient materials have been developed. But we seldom see the paper about that FGMs are produced by making use of laser. In this paper, we make FGMs with laser in self-propagating high-temperature synthesis. We select nickel and aluminum powders, which can react and release much heat. The ignition time and reaction time are shortened. And the highest temperature which reaction can get is improved. Utilizing the laser of high power density, we can get more complete product. And the composite process of phase in this method is different from that in tradition method.
