Abstract
High reflective metal materials have some disadvantages on laser heat treatment.In order to increase the laser absorption of metal materials, the effect of external applied electric field on the laser absorption was studied.A so-called saturated temperature technique was put forward to measure the laser absorptivity of 2Cr13 stainless steel with external applied electric field applied.The test results indicated the external electric field could increase the laser absoptivity of metal materials.
