Characterization of Surfaces and Coatings Using Laser-Generated Ultrasonic Surface Waves

摘要

Metallic coatings are produced for various purposes, and methods employed for testing their quality vary accordingly. Many tests have been developed in the past to determine the various properties of the coatings. Wear-resistance tests are commonly carried out on metallic deposits, plated specifically as a protection for the metal substrate against wear and erosion. A typical example is chromium plated on steel substrates.
