Investigation of 2550 Cold Work Tool Steel Coated with TiN and CrN by PVD Method by Scratch Method
Journal Title: International Journal of Engineering and Science Invention - Year 2018, Vol 7, Issue 12
Abstract
Rapidly developing PVD (Physical Vapor Deposition) coating process is applied in many industrial applications. Coating surfaces are important in many cases. Coating may increase functionality of bottom layer. In many cases, depending on adhesion of material and coating, base material makes important contribution to mechanical properties of materials. In PVD process, coating process is performed at low temperature and a homogeneous structure is obtained. Bonding forces of base material and coating material play an important role in maintenance of coating without deformation. Scratch test is performed to evaluate hardness and adhesion properties of thin films. DIN 1.2550 cold work tool steels, which are used in cutting, pattern, mint molds and scissor blades, and are subjected to wear, are generally used by coating with PVD method in usage areas. In this study, it was aimed to determine the effect of coating on hardness and adhesion ability of DIN 1.2550 material with coated TiN and CrN by PVD technique. Also, sections of test specimens were examined by scanning electron microscope (SEM) and thickness of coating was measured in the study. Surface roughness and hardness measurements were performed after coating process. A nanoindenter and a scratch tester were used to evaluate hardness and adhesion properties of thin films. For this purpose, samples were covered with TiN and CrN thin film by using cathodic arc PVD technique, and results were evaluated by performing hardness and scratch tests.
