Hot Affect Region of Base Clad by Laser Beam and its Repeated-Impact Properties

Abstract:

The experiment result of base of laser cladding samples shows that more energy base absorb, more wide the Hot affect region. The base with the quenchable material will be quenched hardening and get refinement organization, such as medium steel, etc. Contrariwise the base of austenite stainless steel doesn’t have these phenomenons. Under the repeated impact load, the quenched hardening base may be softened and appear flaw easily, such as crack, etc. The base of low stiffness may be hardened in a distance.
