Abstract

In today's industry, cutting tools used in the machining sector have an important place in terms of lifespan, durability and working performance. Cutting tools used in almost all sectors not only constitute a large portion of company expenses, but are also a permanent expense item. Therefore, thin film coatings are frequently preferred to increase the performance of tools produced in various materials and geometries, improve their life and reduce the cost expenses allocated to cutting tools. Magnetron sputtering method allows obtaining hard thin film coatings at lower operating temperatures compared to other methods and is among the most preferred applications, especially in the mold and cutting tool industry. TiN thin films are an important coating type used in cutting tools. The coating method and coating parameters directly affect the mechanical properties of the resulting coating. The characteristics of the power source used in the coating process also play a decisive role. In this study, the effect of DC and Pulse power sources on TiN coating properties was investigated. TiN thin films were deposited on HSS-E substrates using DC and Pulse power supplies, and then their roughness and hardness values were examined. It has been determined that TiN thin films deposited using DC Pulse power supply have better hardness values and increase tool life.
