Tic Carbide Production Process
Tic carbide production process is TiC, Ni and Mo (or Mo2C) together with wet grinding, green compact usually in the vacuum at 1300 ~ 1500 ℃ for liquid phase sintering; can also be infiltration method and high temperature from Spread synthesis method. TiC-Mo2C Ni alloy was prepared by infiltration method. The TiC porous sintered body (skeleton) was prepared by infiltration method. Then, Ni, Mo melt was used to melt the skeleton to form dense sintered body. TiC-Mo2C was prepared by high temperature self-propagating method Alloy, the titanium powder, carbon black, molybdenum powder and nickel powder were kneaded, dried and pressed, and then subjected to high temperature self-propagating reaction in the graphite mold and maintained at a load of 0.05 MN after the combustion wave was passed 6 ~ 10s. TiCN Carbide is essentially a variant of Tic Carbide, and its preparation process is essentially the same, including the preparation, forming, sintering or hot pressing of the mixture. When the mixture is prepared, Tic and TiN can be mixed with TiC and TiN Can be added in the form of Ti (C, N) solid solution.

how TiC rods increase wear life of high manganese wear parts
Lost-foam casting (LFC), Policast Process,Evaporative-pattern casting is a type of evaporative-pattern casting process that is similar to investment casting except foam is used for the pattern instead of wax. This process takes advantage of the low boiling point of foam to simplify the investment casting process by removing the need to melt the wax out of the mold.
Physical and mechanical properties of Steel bonded carbide
Physical and mechanical properties of Steel bonded carbide The steel bonded carbide has a high hardness in the hardened state,and its abrasion resistance is comparable to that of the high cobalt cement (even higher material strength and impact resistance than the average cemented carbide).This is due to It contains high (35% ~ 50%) of the hard phase TiC,but also because the circular TiC crystal at work with the workpiece surface to form a rolling friction coefficient, so as to avoid adhesion wear and abrasion wear, so that With high wear resistance and less destructive.The cemented carbide also has a small specific gravity (titanium carbide-based steel is generally lighter than steel),high specific strength, good self-lubricating,high damping characteristics and inherent frequency (with excellent shock effect).

Research Status of Cermet Coatings
Metal and ceramic materials have their own unique excellent performance and obvious performance weaknesses, how to metal and ceramic materials, the advantages of their respective advantages, has been the material science and engineering research direction. Metal ceramic composite coating technology, that is, the plastic matrix evenly distributed with the shape of particles, the size of the appropriate ceramic phase, the successful realization of the advantages of metal and ceramic combination, the preparation of both the strength and toughness of metal, but also ceramic high temperature , Wear-resistant, corrosion-resistant and other advantages of composite materials, greatly broadening the metal materials and ceramic materials, their respective applications in the aviation, aerospace, chemical, mechanical, power and other industrial applications have been successful [20] [21]. In the industry, the most widely used metal-ceramic coating are: Cr3C2-NiCr, WC-Co. Most use HVOF, plasma and explosive spraying process.
ceramic knife
Our company produced the carbide cutting wheel is the use of ultra-fine tungsten carbide, cobalt and other metal and metal carbide powder powder metallurgy produced by a method of ultra-fine grain carbide cutter wheel, product plane, blade Mouth, the inner circle are fine grinding, high precision, cutting more stable, crossed straight, high wear resistance, not collapse edge, gold part of the titanium, increase the hardness, improve the service life.
TiC steel bonded carbide products process characteristics
TiC steel bonded carbide products process characteristics The main properties of steel-bonded cemented carbide are between steel and cemented carbide. It has both the characteristics and strengths of both materials, and is a new engineering material that fills the gap between them. Compared with the steel it has its incomparable high hardness, high wear resistance and hardenability, (steel alloy after quenching, the material from the center to the surface hardness difference of not more than 2 °), which is by its material The particularity of the structure and the unique characteristics of the hard phase of the decision; at the same time it also has just similar to the Machinable, heat treatment and the advantages of welding, these performance characteristics are basically the general carbide does not have The Therefore, it is also possible to use a cemented carbide as a processable, heat-treatable cemented carbide.
