Carbide ideal tool
Carbide is the most widely used class of high-speed machining (HSM) tool materials produced by powder metallurgy processes, consisting of hard carbides (usually tungsten carbide WC) particles and relatively soft metal binders composition. Currently, there are hundreds of different WC-based hard alloy, most of them using cobalt (Co) as a binder, nickel (Ni) and chromium (Cr) is a commonly used binder element, you can also add other Some alloying elements. I produced the carbide has become an ideal tool material.
Application of Tool Coating in Shaft Machining
Steyr through the shaft for the bridge on the important transmission parts,transmitted to the role of the rear drive axle.The quality of a direct impact on vehicle quality is normal or not.Input spline original drawing structure for the rectangular spline, processing technology: rolling rectangular spline a – grinding cylindrical c – knurled key d – heat straight after the c – grinding rectangular spline a. In 2007, the company tried to change the str through the shaft spline involute spline, and a small batch of trial processing, processing technology as follows: hot pre-grinding cylindrical b – rolling involute spline a —- Hot pre-grinding cylindrical c – knurled key d – hot straighten c – hot straighten b, spline connection to involute, eliminating the original rectangular spline grinding cracks, but the phenomenon Need to add an external grinding process before the hot c, but also because of the heat after the need to meet at the same time a, c at school straight precision, to the processing of great difficulties, and the production efficiency is affected to some extent.
Characteristics of TiC-based Steel Bonded Cemented Carbide combined High Manganese Steel
Characteristics of TiC-based Steel Bonded Cemented Carbide combined High Manganese Steel TiC-based steel-bonded carbide and high manganese steel has a good moisturizing effect.The TiC-based cemented carbide and high manganese steel have the same composition as Fe and Mn.The surface of the alloy is Mo2C,which can improve the wettability with the steel matrix.By quenching,the steel matrix in the alloy is transformed into Martensite and a small amount of retained austenite,alloy hardness and strength are greatly improved.Alloy cast in the high manganese steel castings, after water toughness can improve its strength and toughness.

Chromium carbide powder characteristics
Chromium Carbide Powder is high melting-point inorganic material with wear resistance, corrosion resistance and resistance to oxidation at elevated temperature (1000~ 1100oC), and is expansively used as thermal spray material to protect the metal surface. Cr3C2 cermet has excellent resistance to oxidation at high temperature.
The feasibility of producing cemented carbide with niobium tantalum is discussed in detail
The feasibility of producing cemented carbide with niobium tantalum is discussed in detail In recent years due to tantalum raw material water up, so that the price of tantalum containing alloy all the way up. But because people think that the role of tantalum in the carbide can not be replaced with other raw materials, so the face of the price rise is seem powerless. We know that the material is very similar to the performance of tantalum is niobium, and a mention of niobium most people will immediately think of alloy brittle However, after a correct understanding of the characteristics of tantalum and niobium, it has been carefully designed to use niobium tantalum or part of niobium tantalum is completely feasible, and even in some alloy types.
