Nitriding of metals - Import export

Nitriding treatment is a chemical heat treatment process in which nitrogen atoms penetrate the surface of the workpiece at a certain temperature and in a certain medium. The products treated with nitriding have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance. The general process of nitriding process :1. Pretreatment: clean, remove oil and dry the metal surface to ensure that the surface is clean and free of impurities. 2. Nitriding treatment: The metal is placed in an atmosphere containing nitrogen and treated at high temperatures to form a nitriding layer on the surface of the metal. 3. Post-treatment: Clean and cool the metal surface after nitriding to remove the residual nitride layer and prevent its oxidation. The nitriding process is of great importance for many industrial fields, such as tool manufacturing and automotive parts manufacturing.

Sturdy and practical linear rails with radial ball bearing sliders. The X-Rail is a family of linear guides with radial ball bearing sliders for applications requiring cost efficiency and high resistance to corrosion. The linear guides with shaped raceways and the linear guides with flat raceways are available in stainless steel or galvanised or nitrided metal sheeting. With the T + U configuration, the X-Rail system can compensate for any axial misalignment in parallelism of the mounting surfaces.

In the WTH 200.2, the following materials can be reliably brazed with active materials in a high vacuum. PCD (polycrystalline diamond) MKD (monocrystalline diamond) CVD diamond (chemical vapour deposition) PCBN (cubic boron nitride) and Hard metals as well Ceramics In the high-vacuum furnace WTH 200.2, our customers manufacture indexable inserts, dressing wheels, rotating tools and turning tools with blades made of natural diamond or MKD for polish turning. The vacuum brazing is flux-free. In the so-called active brazing process, titanium allows wetting of the surfaces. While cemented hard metals can also be inductively brazed, diamonds, CVD and ceramics must be actively brazed in a vacuum. When brazing PCD and PCBN, not only the hard metal substrate but also the PCD or PCBN layers are wetted.
