Abstract
PURPOSE: To give blade for compressor hardening treatment by laser irradiation to improve wear-resistance and fatigue strength.
CONSTITUTION: The whole surface of blade which is used for valve part of compressor to feed into refrigerant gas is given impact-hardening treatment by irradiating laser. By doing so, wear-resistance and fatigue strength can be improved compared to that with no laser treatment. In this case, laser hardening treatment is favorable as it would not deteriorate the surface condition nor it creates evil effects such as transormation or distortion like other hardening methods do, and laser is capable of applying treatment only on the desired spot as its output or irradiating part can be appropriately selected. These are effective not only for valve steel used for ordinary blade but also for blade of various special steels
