How to characterize a thermal spray coating using electron microscopy.(HOW TO ...)

Despite all of the advances in metallographic techniques over the past two decades, there are still a number of coatings that cause problems within the metallography lab. Frequently, these coatings will take on different appearances based on the preparation recipe used. From a metallography standpoint, there is no single method that can be relied upon to prove the true structure of the coating. Fortunately, there are simple alternatives to metallography that can be used to characterize a thermal spray coating. This article will discuss one such method, which involves using a scann
