Review on Effects of Photo-Processes in Painting of Machines Metals

Nawfel Muhammed Baqer Muhsi


This review conversed about Photo-processes on machines, photo-treatment is a group of metallurgical processes to improve the physical and sometimes chemical properties of steel, iron ore and this results in controlling the hardness and ductility of the solid product. The photo- treatment is divided into several sections, each according to the way of cooling as all types of heat treatment are similar in the heating stages, except that they differ in the cooling process. One of the reasons why metals are so widely used is the wide range of mechanical properties in which they are chosen.  

Keywords: photo process , photochemistry, corrosion, photo, photo-pollution, machines.
