What is chain surface hardening treatment

Technology introduction TBM technology is a new surface hardening treatment technology developed in recent years with a deeper hardening layer and a wider range of applications. The depth is 0.01-0.2mm. The surface hardening layer has a hardness of 1500-2400HV. The hardening layer is dense and impact resistant. , Combined with the base metal metallurgy, the wear resistance of the surface hardened layer greatly exceeds the common surface treatment technologies such as nitriding, carburizing, carbonitriding, and hard chromium plating. The metallurgical combination of the hardened layer and the base metal far exceeds the hard plating Chromium, load-bearing capacity and temperature resistance (below 800°C) exceed the characteristics of TD coating treatment. It has extremely high wear resistance and anti-adhesive properties, which can increase the service life of workpieces by more than several times, and can process various steel materials. Cemented carbide and steel bonded cemented carbide, nickel-based, cobalt-based, tungsten-based, molybdenum-based, titanium-based and other special alloys.
