Abstract
Boron steels are used in hot stamping process due to their good mechanical properties. During the stamping process, the dies are exposed to aggressive conditions including adhesive wear, thermal stresses, fatigue, and abrasion. In the present work, there are three samples with different HRC. One sample will use different procedure of preparation which is using quenching that self-hardening while other two used hot stamping. Then all samples are coated with Aluminium Chromium Nitride (AlCrN) using Physical Vapor Deposition. After that, the samples coating were characterized and tested using Scanning Electron Microscopy (SEM), wear test by using pin on disc, hardness test and microscope for measure flank wear. By using SEM, the width of the stroke becomes smaller when using hot stamping process. For the hardness test, the Aluminium Chromium Nitride (AlCrN) stronger than others because using hot stamping process. Wear resistance of coatings increase due to the decreasing of coefficient of friction obtained. While others suggest that the transformation of the layer into produce marten site phase and more harder is the ultimate responsible for such changes. These three samples will make a comparison and find the best by using different parameter for machining. The best will go further to machining process. The expected results in term of hardness and wear which are using hot stamping with higher HRC of sample will be better than others.
