Global markets and applications of superabrasive materials

作者：Terry M Kane 刊期：2008年第S1期

Superabrasive is a term globally applied to any one of a category of superhard materials.The first"super"abrasive was natural diamond,which was found,due to its many properties,to be excellent for the removal shaping or cutting of less hard materials,especially carbide,glass and stone.Then in 1954 diamond could be ma...

The overview of industrial diamond in Korea

作者：Lee Yoon-Young 刊期：2008年第S1期

Introduction Industrial tools using diamonds were first introduced in the Korean market about thirty years ago.In the beginning,diamond tools were primarily used in industries dealing with stone materials.Today,however, they are focusing more on industrial tools than construction tools.The production trend of the Kor...

Detonation nanodiamond and its applications:A case from China

刊期：2008年第S1期

Nanodiamond is a new material which has the dual properties of diamond and nanomaterial.The dual properties have contributed to its wide applications in many industrial sectors.This paper briefly reviews the development of nanodiamond,describes its synthesis technology under dynamic high-temperature and high-pressure...

A comparative study on the performances of synthetic diamond made by belt press & cubic press

刊期：2008年第S1期

There are mainly two kinds of equipment to produce synthetic diamond,namely belt press & cubic press.It has been customary in the industry to regard synthetic diamond produced by cubic press is inferior to that made by belt press.With the on-going improvement in technology,know-how & accumulated experiences, perhaps ...

Microstructure and properties of the sintered diamond reinforced by diamond-MWCNTs composite fibers

刊期：2008年第S1期

Characterization of diamond MWCNTs composite fiber synthesized under high pressure and high temperature

刊期：2008年第S1期

A regrown composite fiber was synthesized during the sintering of diamond under high pressure 5.8 GPa and high temperature 1500℃for 1 min,using 3wt%MWCNTs as additive.SEM observation of the fiber after alkali and acid treatment revealed that the outer layer of the fiber is composed of nano-polycrystalline diamond.ED...

Study on doping effect of interface binding state in the system of PCD and PDC at superhigh pressure

刊期：2008年第S1期

Experimental and theoretical researches on the doping effect of interface binding state with homologous and heterogeneous dopants(d) in the system of PCD etc,as well as the action of intermediate layers between D /d at superhigh pressure and high temperature(HP-HT) are reported in this paper.

Ultrahigh pressure sintering of polycrystalline diamond cubes

作者：Hu Shao-Chung Chang Kuen-Liang Sung James C. Tso Pei-Lum Hsu Kai-Hung Sung Michael 刊期：2008年第S1期

Polycrystalline grits(polygrits) have been used widely in industry as abrasives.Due to their higher impact strength and the friable nature,polygrits are more endurable and more efficient than monocrystal grits (monogrits) in material removal applications.For example,polygrits of alumina may last longer and cut faster...

Improved impact resistance of PDC and test of it in laboratory

作者：Choi Dong-ik Park Byong-joon Oh Jeang Ook. 刊期：2008年第S1期

A study is performed on a newly developed Polycrystalline Diamond Cutter(PDC) with improved impact resistance.Impact resistance of PDC is dependent on diamond grain size,binder content and property of the substrate.A crack might initiate in the substrate by the impact transferred from the diamond layer if substrate i...

High speed continuous turning of hardened steel with newly developed low content PCBN

作者：Lee Sang-Yong Park Byong-Joon Oh Jeang Ook 刊期：2008年第S1期

In this study,newly developed low content PCBN was used to evaluate the cutting performance in high speed turning of hardened steel.Using new PCBN and commercially available PCBN tipped inserts under the same cutting condition,cutting performance with variable cutting speed,feed rate and depth of cuts on tools were m...

Polycrystalline diamond mini-cubes for sawing applications

作者：Sung James C. Chang Kuen-liang Tso Pei-lum Hsu Kai-hung Sung Michael 刊期：2008年第S1期

Diamond grits are indispensable for sawing granite or concrete.Each year about 1 000 tons of diamond grits are consumed for such purposes.In all cases,mono crystalline diamond is used.However, polycrystalline grits(polygrits) are generally better performed than mono grits as abrasives.For example,poly grits of cubic ...

Residual stress and radial stress gradient in polycrystalline diamond compacts

刊期：2008年第S1期

The differential thermal expansion of the polycrystalline diamond layer and the tungsten carbide substrate results in large residual stresses as PDC cutters cooling after sintering.The residual stresses on the top surface of the diamond layer of PDC were measured at five points along the radial direction of PDC using...
