The current trend of machine tools is high speed, high precision and high quality. High-speed operation requires more and more surface treatment of molds, cutting tools, and mechanical parts. Extending the service life, reducing production costs, and creating higher profits are the common goals pursued by the industry.
The number of ceramic hard films developed by PVD technology is increasing, including titanium nitride, titanium carbonitride, titanium carbide, aluminum oxide, diamond-like films, and titanium aluminum nitride. Such ceramic dura mater is currently applied to a tool or a mold, which not only improves the wear resistance of the tool surface, but also does not lose the toughness of the metal substrate. With the recent breakthrough in machine tool technology, cutting has been speeding up to shorten the cutting time and improve the surface precision of the workpiece.
In order to cope with high-speed machining and save a lot of processing time and cost, tool improvement has become an important factor. Tungsten carbide tools are increasingly used in the tool market due to their high wear resistance and hardness. In order to obtain the best benefits during processing, proper surface treatment must be selected. Medium and heavy-duty molds must be CVD high-temperature titanium, supplemented by precision vacuum heat treatment to achieve acceptable deformation. This part is often used for cold forging dies, hydraulic drawing dies, tungsten carbide drawing lines, and suction pipes. In the application of tools, molds and mechanical parts with medium, low load or high precision requirements, it is appropriate to use low temperature (150 ° C ~ 500 ° C) PVD titanium plating.
Aluminum nitride having a high aluminum content easily forms alumina on the surface of the hard film. This layer of oxide film can make the aluminum oxide titanium ceramic hard film have an oxidation resistance temperature of 923 degrees Celsius, which can protect the edge of the tungsten carbide tool from high oxidation resistance and maintain high temperature hardness. However, although titanium nitride and titanium carbonitride also form a titanium oxide film at a high temperature, they do not easily adhere to the hard film and peel off with the chips, so that the hard film lacks protection, rapid oxidation, and deterioration. Therefore, regardless of the surface treatment of high-temperature or low-temperature coating, it is necessary to select an appropriate substrate and a stable heat treatment, supplemented by pre-treatment of surface fine grinding and polishing, in order to improve.
