Metal powder metallurgical technology ceramic materials mainly include ceramic materials metal powder metallurgical technology ultra fine cemented carbide, special hard phase hard alloy, of functionally gradient hard alloy, hard alloy heat treatment, coating hard alloy, new technology and new technology and new equipment, and Ti (C, N) fund of ceramic, etc.

1, metal ceramic materials of powder metallurgical technology submicron cemented carbides

To make the whole hard alloy material also has excellent toughness and wear resistance, at present mainly for super fine until nanocrystalline hard alloy materials. Refine the grain and main method is to add a limit of grain growth inhibitors. Especially control small grain WC), it is one of the crack source.

2 ceramic materials, metal powder metallurgical technology in the special hard hard alloy

Ceramic materials metal powder supplier metallurgical technology in the special hard hard alloy mainly includes the disk hard phase strengthening hard alloy and the petronas twin structure hard alloy. The disk hard phase strengthening hard alloy is to point to will ordinary hard alloy are tri-prism body or more of a body of grain prismatic WC underside (0001) surface according to grow up, and change the plate to the triangle.

3 ceramic materials, metal powder metallurgical technology functionally gradient of hard alloy

To improve the properties of cutting tools, the function of functionally gradient materials design ideas into the hard alloy tool material field, manganese powder in order to realize the material surface area has good abrasion resistance, interior has good fracture toughness, gradient composition layer obtained inside the residual stress compression. Although coating hard alloy as both of both properties material, but the need for ceramic coatings for the special process, and there is a high cost. The surface, this new materials with uniform than ordinary metal coating of high wear resistance, fracture toughness and crack resistance to sex.

4 ceramic materials, metal powder metallurgical technology of cemented carbide heat treatment

Hard alloy heat treatment due to make hard alloy products the whole volume happens inside structure and the change of the performance and improve the overall performance of the alloy. The results indicate that the heat treatment can significantly improve the mechanical properties, boron powder wear resistance and fatigue strength, to make the hard alloy service life greatly improved.

5, metal ceramics powder metallurgical technology of cemented carbide coating

Ceramic materials metal powder metallurgical technology of cemented carbide products surface coating, silicon powder coating technology is developed in recent years to an advanced technique, hard alloy field of a landmark important technical breakthrough. Hard alloy products surface coating, coating technique appears to solve hard alloy wear resistance and toughness of contradictory article provides a more efficient way. At present, improve and develop the research on the effect of coating work basically along two direction: one is the perfect making wear-resisting coating equipment and process; Two new components is developed for coating, and explore the new wear-resisting coating material.

6 ceramic materials, metal powder metallurgical technology of the new technology and new technology and new equipment

In order to adapt to the hard alloy improve product quality and more variety of needs, nickel powder in further improve and perfect the hard alloy production technology and equipment, but also to develop new technology and new technology and new equipment. Like high temperature self-propagating synthesis technology, plasma system powder technology, fluidized bed pelletization techniques, injection molding technology and other new forming technique, plasma sintering technology, copper powder(FCu) microwave sintering technology, all kinds of new type chemical and physical vapor deposition technology and various strengthen treatment technology, etc.

7, metal ceramic materials of powder metallurgical technology Ti (C, N) fund of ceramics

Metal ceramic materials of powder metallurgical technology Ti (C, N) fund of ceramics in fund of ceramic TiC is developed on the basis of, make Ti (C, N) fund of high temperature ceramic with excellent and wear resistance, good toughness and strength of the new metal ceramics. Vienna, Austria industrial university found in Kieffer TiN TiC-Ni series materials after the notable effects, the TiC of fund did not appear in the report into TiN ceramic. Source:www.mhcmp.com
