摘要: Advanced industrial applications require materials with special surface properties such as high corrosion and wear resistance hardness. Alloys possessing these are usually very expensive their utilization drastically increases the cost of parts. On other hand, failure or degradation engineering components due to mechanical chemical/electrochemical interaction surrounding environment is most likely initiate at because intensity external stress environmental attack often highest surface. The solution prevent minimize region a component through procedure known engineering. Conventionally practiced techniques like carburizing, nitriding, etc. material specific, time/energy/manpower intensive lacking in precision. Among techniques, relatively new attractive method laser treatment. In words, treatment offers an excellent scope for tailoring microstructure and/or composition proves superior conventionally For application, laser, simple terms, can be regarded device producing finely controllable energy beam, which, contact material, generates considerable heat. basic physics simply heat generation by absorbing subsequent cooling either conduction into interior, thermal reradiation temperatures from material. Various methods that currently available shown figure 1.
