Analysis of the AFP Process AFP is a process that combines chemical erosion and mechanical abrasion thus is suitable for machining various materials.
Material removal, based on the above analysis, is mainly from the chemical erosion and mechanical abrasion while the deposition rate of passive film protects against the material removed from the wafer.

In this study, corrosion property of both weld metal and base metal was investigated with some electrochemical methods in natural sea water solution, in case of being welded with some welding methods and welding materials to the exhaust valve specimen as the base metal.
In this study when repair welding with various welding methods and welding materials like foreign and domestic electrode was performed at the exhaust valve part as the base metal, corrosion property of both base and weld metal were investigated with some electrochemical methods such as corrosion potential, polarization curves, cyclic voltammogram etc.. 2.
Experimental procedure Ni-Cr steel(KS:STR-3) was used with base metal(BM) and stellite electrode was also used for repair welding materials with foreign and domestic electrode respectively.
Conclusions When repair weld was performed at the exhaust valve with some parameters such as welding methods, welding materials, corrosion resistance between base metal and weld metals was investigated with electrochemical view point.
Corrosion resistance of weld metal irrespective of welding methods and welding materials was clearly superior to the base metal.

The result concluded in this paper shows that the optimized particle swarm algorithm can achieve ideal material utilization.
Layout technology has been used as the most important way to raise the material utilization ratio, reduce the material loss and production cost for garment manufacturing enterprises in the production process .Therefore, a set of intelligent and efficient layout technology can not only reduce the staff’s working strength, but also greatly improve the producing speed and the utilization ratio of material, and but also bring considerable economic benefit to enterprises.
