The characteristic and distinguished method of two classificatory cemented carbide binder is expatiated.It is recommended that GBY is a new cemented carbide binder.
Taking the superfinishing of thin-wall hole machining as an example, the design and application of combined carbide core drill and reamer are introduced.
Although PM has solved the problem of carbide segregation and crassitude fundamentally, it has complicated technics and extortionate cost, so restricts its application.
Transformation mechanism of carbides and their effect on the stress rupture property were investigated in a Ni-base single crystal superalloy with microcontent of carbon.
The catalysts on studying can divide into two kinds: the transition metal bifunctional catalysts and the nitride, carbide and oxycarbide catalysts of transition metals.
The crack initiates at stress concentration point in the root of weld, where has much more martenite, carbide and inclusion, and the serious hydrogen segregation.
The characteristics of each cement clinker process by carbide slag in domestic were analysed. dry prebaking, dry grinding, and dry burn process are best prospective.
It has properties of hardening after malleablization,arc welding and impact resistance.It can grind but can not machining demagnitized steel-bonded carbide.
It is proved that the pressmark of tooth root, the state of carbide and remanentelements in the material have different effects on the toughness of POwer hacksaw blades.
The results of research show that the impurity of infusibility and metal ion has been removed after the leaching of calcium carbide residue, and the transform rate of hydrated lime up to about 88%.
For some batches, the calcium chloride and urea have been successfully substituted, respectively, by carbide sludge, an industrial waste, and human urine.
Chipmakers hope gradually to replace the silicon used in most processors with gallium nitride or silicon carbide, both of which can handle higher voltages.
The reactors use " tristructural isotropic particle fuel" , in which blobs of fissile uranium (along with oxygen and carbon) are wrapped in layers of carbon and silicon carbide.
