Physical vapor deposition (PVD) coatings are widely used in cutting tools due to their good wear resistance. Engineers and technicians have made significant progress in the development of PVD coatings, thanks to the phenomenon of “cross-fertilization†– that technological advances in one research area can increase demand in other markets. For example, the tool market can benefit from advanced coatings developed for the automotive engine market. Recently, Hauzer Techno Coating, a PVD coating technology development company in the Netherlands, has applied its antifriction coating technology to the tool market and achieved excellent results. In many tooling operations, the hardness and good adhesion of the coating is critical. However, other properties of the coating can also be an advantage. For example, when processing softer workpiece materials such as aluminum or plastic, the non-stickiness of the coating is important because it extends tool life and increases the productivity of the processing equipment. In other words, a smooth surface can be a great advantage for forming tools because it omits subsequent machining of the workpiece. These properties have been extensively studied in automotive coating applications, with the result that coating performance is continuously optimized. Diamond-like carbon (DLC) coatings have excellent tribological properties and are widely used in automotive parts processing. The DLC coating has a low coefficient of friction and is not easily bonded to the workpiece material. With different coating deposition techniques (magnetron sputtering, PACVD, arc evaporation, etc.), coating characteristics suitable for processing requirements can be obtained. DLC coatings are ideal for coating drills, inserts, end mills, saw blades, taps, punches, injection molds, and more. In addition to processing aluminum workpieces, DLC coatings can also be used to machine other non-ferrous metals and plastics. Another example of the transfer of technology from one market to another is the hydrogen-free DLC (ta-C) coating. During the implementation of the nanocoating project (Nanocoat, a European research project with the goal of developing various nanostructured coatings using environmentally friendly deposition techniques), at the Fiat Research Center (CRF) in Turin, Italy, coating Several DLC coatings on automotive engine parts (mast) were tested. These tests concluded that the ta-C coating has the highest hardness and the lowest coefficient of friction. Hauser, one of the partners in the nano-coating project, has been able to solve the problem of adhesion of ta-C coatings using the knowledge gained from the project. As a result, industrial applications of various ta-C coatings having excellent adhesion (DB 1-2) and hardness values ​​(40-70 GPa) were achieved. In an impact test conducted by a major US engine manufacturer, the ta-C coating remained intact under 2kN impact loads, with only minor microscopic cracks visible to the naked eye. Under the same impact load, the coating as a reference has been peeled off. The Rockwell indentation photo shows that the ta-C coating has excellent adhesion. This hydrogen-free ta-C coating is prepared by an arc (arc or arc) evaporation process and has a diamond-like structure (mainly SP3). Typical hardness of ta-C coatings is 3,000-7,000 HV with a typical coefficient of friction of 0.02-0.1. Hauser believes that the excellent properties of ta-C coatings, coupled with the successful resolution of coating adhesion, make it a promising precision tool coating.
