Laser Pulse Heating Simulation of Firing Damage on Coated Gun Bore Surfaces

摘要

Laser pulse heating was used to simulate thermal effects on plated gun bore surfaces during firing. The aim is to provide new insights into the erosion process and develop the method as an evaluation tool for developmental coatings. This report discusses results of cyclic thermal pulsing experiments on high contractile and low contractile chromium plated gun steel, sputtered tantalum coated gun steel, and uncoated steel.
