Abrasive Particle Wear Research Of Die Steel Processed To Bionic Non-smooth Surface By Laser

The energy sources wasted by the way of friction finally are about 33 or 50 percentage of the world's energy. The research of the rubbing abrasion and lubricating question will account for the tremendous economic effect. Therefore, many country scientists' great efforts to improve the wear resistance of materials have been very effective. Great development has been achieved in the abrasion and wear assistance of materials. However, it was considered when the smoother the surface of materials was, the smaller the conglutination force to other objects was and so the abrasion resistance during the relative movement was smaller in tradition theory. As a result, the surfaces of the work parts or products which are required to reduce the abrasion resistance or conglutination will be designed to be smooth ones. But the effect was not very obvious.The bionic research indicates that the rough surfaces of some animals result in reducing the wear resistance with great efficiency. The structure and performance of the kind of animals are very particular after hundreds of millions evolution, which accords with their subsistence circumstance. Many researches have indicated that the animals live in the marshy soil whose bodies are characteristic of geometry rough surfaces. The rough surfaces can result in reducing conglutination, lessening resistance and increasing resistance wear. The tribology and bionic investigations show that the wear resistance of the smooth surfaces will not be best, the other way round, the resistance wear of the non-smooth surfaces may be better. To increase the resistance wear of materials, the investigation is attempted to carry out the non-smooth configurations of material surfaces.The researches of the non-smooth configuration of the soil animal body surfaces...
