Description
Summary:Abstrac t—The effect of ultraviolet (UV) laser radiation on the structure and adhesion properties of materials such as chromated bronze, stainless refractory austenitic chromium-nickel steels, and copper, has been experimentally studied. It has been shown that the surface microstructuring of elements of a diffusion-bonded joint improves its mechanical properties as to its tensile strength and tensile strain. Some results are presented for the laser perforation of a copper interlayer and the laser surface microstructuring of ceramic blanks which provide improvement in the mechanical properties of a Si 3 N 4 /Cu/Si 3 N 4 welded joint.
