Diamond PDC substrate is a kind of diamond and cemented carbide matrix composite material, which has the advantages of high hardness, good wear resistance, etc. Compared with the general cutting tool materials such as high speed steel and cemented carbide, the diamond PDC substrate material has the advantages of extremely high hardness and wear resistance, low friction coefficient, excellent thermal conductivity, small thermal expansion coefficient, high elastic modulus, etc., which makes it an ideal material.
Whether it is machining, geological exploration, oil extraction, metallurgy, or aerospace, national defense and military industry as well as photovoltaic and electronic information and other fields in a variety of difficult materials processing problems, in front of the diamond PDC substrate are solved.
With the development trend of wood processing and other industries have been the use of automated machine tools to replace the traditional manual mode of operation, the requirements of the tool is higher, diamond PDC substrate then use more, what are the characteristics of it can be favored by everyone?
1.Extremely high hardness. Diamond is one of the hardest materials on earth, its hardness is far more than other natural minerals. The hardness of polycrystalline diamond is HV7500~9000, second only to natural diamond. Moreover, its hardness and wear resistance are isotropic and do not need to be oriented. Its strength is supported by high toughness cemented carbide, and its composite flexural strength can reach 1500 MPa.
2.High wear resistance. The wear resistance of polycrystalline diamond is higher than that of cemented carbide. Extremely durable when cutting non-metallic materials with high hardness. Suitable for environments that require resistance to abrasion and scratching.
3.Has a low friction factor. The friction factor between polycrystalline diamond and non-ferrous metals is 0.1~0.3, while the friction factor between cemented carbide and non-ferrous metals is 0.3~0.6.
4.Diamond has excellent thermal conductivity, which can effectively transfer and disperse the heat and prevent the material from overheating. It has superior performance in high temperature environment. It can greatly reduce the temperature in the cutting zone and improve tool durability.
5.Chemical inertness: diamond remains stable under the erosion of many chemicals, so diamond PDC substrate can work in some corrosive environments without being seriously affected.
6.Excellent Mechanical Properties: Diamond PDC substrate have superior mechanical properties, including high strength, stiffness and tensile resistance. This allows them to excel in applications that require them to withstand high loads and pressures.
7.Optical Properties: Diamond has a high refractive index and dispersion, giving it some potential for optical applications. Diamond PDC substrate can be used to make optical lenses, windows and other optical components.
8.Electrical insulation: Diamond is an excellent electrical insulator and is suitable for a number of applications that require electrical insulation properties.
9.Biocompatibility: Diamond PDC substrate can be surface treated to make them more biocompatible. This gives them potential for use in medical applications such as biosensors and medical devices.
10.Lightweight: Despite its hardness, diamond has a relatively low density, so diamond composite piece are relatively lightweight and can sometimes be used in applications where strength and hardness are needed while keeping weight low.
11.Has a small coefficient of expansion.
12.Can be fabricated in a variety of sizes and shapes as needed.
13.Superior toughness and impact resistance.
Overall, the properties of diamond composite laminates give them the potential for a wide range of applications in a variety of fields, including industrial, electronics, medical, and optical. However, the manufacture and processing of diamond composite sheets usually requires advanced technology and equipment, and as a result they can be relatively expensive.
