New technologies have emerged in forensic science and their application in solving trace evidence problems is intended to solve some of the limitations encountered when solving specific analytical problems. This article proposes that in cases where thermal spray painted objects are suspected to have been involved in the course of a crime, surfaces of objects with thermal spray painted coatings should be tested for the presence of trace materials because this approach will offer valuable clues during the investigation process. Different trace materials attach themselves on different surfaces based on the features on the surfaces of trace materials. Also, the features of the surface onto which the trace material will be attached affect the adhesivity of trace materials. This article proposes that there should be research on the way different trace materials are attached on thermal spray coatings based on the hardness, density, and porosity of the coatings. The article proposes that adhesion of surface materials will affect the ability of trace materials to be attached to the surface of thermal spray paints. The article also proposes that collecting trace evidence on surfaces of thermal spray paint coatings.
