titanium carbide-bonded carbide rods Product advantages
Using high-purity manganese powder, iron powder, nickel powder and the company’s own production of high-purity titanium carbide powder as raw material to ensure that the TM52 titanium carbide titanium carbide-based carbide rods of product quality;
CNC tool main material types
(2) ceramic cutting tools. Ceramic tool has a high hardness, wear resistance and good high temperature mechanical properties, and metal affinity is small, easy to produce bonding with the metal, and good chemical stability. Ceramic cutting tools are mainly used in steel, cast iron and its alloys and difficult processing of cutting materials, can be used for ultra-high-speed cutting, high-speed cutting and hard material cutting.
Application of arc spraying anticorrosive technology in steel structure
Due to its advantages of good mechanical properties, strong bearing capacity, easy manufacture, easy to adopt industrialized production, short construction and installation cycle and good sealing performance, the steel structure has been widely used in the national economy construction such as large-span structures (bridges, stadiums Roof truss,etc.), light steel structure (medium and large workshop), high-rise building (New York World Trade Center and Shanghai Jinmao Building, etc.), shell and shell structure (pressure vessel and long-distance pipeline). However, during service, the steel structure is prone to chemical, electrochemical or physical effects with the environment medium in which it is located, causing deterioration of the material and failure of the steel structure, which is often referred to as corrosion of the steel structure.
Zirconium carbide powder characteristics
Zirconium carbide, chemical formula ZrC, relative atomic weight 103.22, the carbon 11.64%, typical of the NaCl type face-centered cubic structure with a lattice constant of 0.46930nm space group Fm3m, C atoms and Zr atomic radius ratio of 0.481, less than 0.59, the formation of simple clearance phase, Zr atoms form a tight cubic lattice, C atoms in the lattice octahedral interstitial sites. Zirconium carbide has a melting point 3540 ℃, the theoretical density of 6.73g / cm3, linear expansion coefficient of 7.2 × 10-6K-1, microhardness 2600kg / mm2, a resistivity of 57 ~ 75 / μΩ · cm, the oxidation start temperature of the strong 1100 ~ 1400 ℃, insoluble in hydrochloric acid, but soluble in nitric acid.
TM52 Titanium Carbide Steel Bonded Rod
First of all, TM52 carbide-based titanium carbide cermet carbide rods cost far lower than the cost of carbide rods, followed by TM52 titanium carbide-based carbide cermet carbide rods and high manganese steel substrate combined to play its greatest role , Carbide with high-manganese steel wear parts, high-chrome wear-resistant pieces of mosaic, the third point of the two different processing methods, titanium carbide ceramic rods are casting process, cemented carbide is generally inlaid process.
The basic structure of arc spraying mold
(1) metal spray layer: The mold products for high hardness polyester plastic products, require the mold has a certain strength, hardness, surface roughness and good thermal conductivity, for which we use a special alloy material as a metal spray material, The mold cavity in the illustration is formed by arc melting spray.
