The first CVD-coated cemented carbide was the single-layer titanium carbide coating (TiC). Alumina coatings (Al2O3) and titanium nitride (TiN) coatings were introduced later. More recently, the modern titanium carbonitride coatings (MT-Ti(C,N) or MT-TiCN, also called MT-CVD) were developed to improve grade properties through their ability to keep the cemented carbide interface intact.

DIC is a useful tool for analyzing very fine deformations that may still be present in the surface after polishing. It can also be used to distinguish hard and soft structural elements, because hard phases are removed to a lesser extent than softer ones during the final polishing process and, therefore, ‘protrude’ from the surface.
