What Is Diamond Coated Carbide?

1. CVD Diamond Introduction Chemical Vapor Deposition (CVD) diamond refers to the use of CVD method, under low pressure conditions, with carbon-containing gases such as H2 and CH4 as the reaction gas, chemical reactions under plasma-assisted and certain temperature conditions, resulting in solid particle deposition Diamond obtained on the heated substrate surface. Similar to natural diamond, CVD diamond is a crystal of a single carbon atom and belongs to a cubic system. Each C atom in the crystal forms a covalent bond with sp 4 hybrid orbital and another 4 C atoms, and has strong binding force and stability. Nature … Read more

Features And Preparation Of Tungsten Carbide Mining Tool

Cemented carbide is a composite material composed of high-hardness refractory metal carbides and cemented metals. Because of its high hardness, wear resistance, and stable chemical properties, it is used in modern tool materials and wear-resistant materials. High temperature and corrosion resistant materials occupy an important position. At present, tungsten carbide-based hard alloys are the most widely used among the carbides produced in the world, with the largest output and the most extensive use. Among them, the WC hard alloy used in mines has been regarded as the “tooth” of the mine development, oil drilling and geological exploration industries, and has … Read more

Properties and Application Of Gradient Cemented Carbide

1. The contradictory characteristics of traditional uniform carbide Cemented carbide is a typical brittle material. The traditional uniform carbide one, the material of the various parts of the uniform composition and organization, the alloy is homogeneous throughout, its performance is consistent. The main components of cemented carbide include various hard phases and binding phases. Hard phases such as phases and solid solutions play an important role in the hardness and wear resistance of alloys. Bonding has an important influence on the strength and toughness of alloys. In general, increasing the WC grain size or increasing the Co content will increase … Read more

5 things about carbide progressive die

The progressive die is composed of multiple stations. Each station is connected in sequence to complete different processes. A series of different stamping processes are completed in one stroke of the press. 1.Overview Progressive die (also called continuous die) is composed of multiple stations. Each station is connected in sequence to complete different processes. A series of different stamping processes are performed in one stroke of the press. After one stroke is completed, the material is moved forward by the punch feeder at a fixed step, so that multiple processes can be completed on a pair of dies, such as … Read more

Heat Treatment of Tungsten Carbide Products

Cemented carbide(hardmetal) is a general term for alloys composed of carbides, nitrides, borides, or silicides of high melting point metals (W, Mo, Ti, V, Ta, etc.). Divided into two major categories of casting and sintering. The cast alloy has high brittleness and low toughness, and has little practical application value. Widely used are sintered alloys, which are generally sintered from tungsten carbide or titanium carbide and cobalt powder and have high hardness, wear resistance and hot hardness. Mainly used to manufacture high-speed cutting and processing of hard materials, in recent years, the use of carbide in the mold industry is … Read more

History And Development Of Tungsten Carbide Rolls

Continuously plastically deformed main working parts and tools on the rolling mill. The roller consists of a roller body, a roll neck and a shaft head. The roll body is the middle part of the roll that actually participates in rolling the metal. It has a smooth cylindrical or grooved surface. The roll neck is mounted in the bearing and the rolling force is transmitted to the frame via the bearing housing and the pressing device. The shaft end of the transmission end is connected with the gear seat through the connecting shaft, and transmits the rotational torque of the … Read more
