Abstract
Although the forging is one of the oldest production method in history, it is frequently used in the manufacturing industry today. Looking at the world in 2019, it is seen that the impact of the forging industry on the gross national product (gnp) was 20%. It is predicted that the forging will increase its popularity as a process that is used for demanding parts that require high strength and are critical to industrial economy, society and national security. Therefore, companies in the sector need to improve their production lines, performance and quality in the product ranges. The most important factor affecting the production performance and quality in the forging process is the damage seen in the forging dies. In the literature reviews, it was determined that the leading cause of damage in forging die was wear. Therefore, it is an undeniable fact that improving the wear resistance of die materials is essential for the forging industry. The most important method developed in this context is the process of covering the material surface with a hard layer. Particularly, it has been determined that the nitride-based layers coated on the surface using Physical Vapor Deposition (PVD) provide unique contributions to the wear properties of the materials. The wear performance of the coated material is determined by using wear mechanisms in a laboratory environment to reflect the working principle of production. However, in the evaluations, it is considered that these devices are insufficient to reflect the forging process, so it is considered inappropriate to evaluate the findings under the current process conditions. In this direction, in order to eliminate this important deficiency, a wear test device which a patent application was also made was designed and detailed analysis was given on how to eliminate the deficiencies of other mechanisms.
