Abstract

High power transverse flow CO₂ laser was used to scan the brazing alloy and diamond grits, the paper studied the influence of laser power on brazing layer combination performance and diamond grits thermal damage, analyzed the thermal damage mechanism of laser brazed diamond and combination mechanism of brazing layer and diamond grits. The research result showed that laser power is one of factors for diamond thermal damage, under high laser energy input, oxidation took place between diamond grits and oxygen outside, diamond would be oxidized all along on the condition of branch gas pressure about free equation until the balance established between diamond and oxide, during this process, diamond grits would be carbonized or burn out and gasify.
