carbide

Boron carbide can be obtained by means of thermal decomposition of triethylborane, tripropylborane and tributylborane, respectively.

The characteristic and distinguished method of two classificatory cemented carbide binder is expatiated.It is recommended that GBY is a new cemented carbide binder.

The rifts at both installation holes of the silicon carbide rod ends shall be blocked by asbest rope.

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 catalysts on studying can divide into two kinds: the transition metal bifunctional catalysts and the nitride, carbide and oxycarbide catalysts of transition metals.

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.

Taking the superfinishing of thin-wall hole machining as an example, the design and application of combined carbide core drill and reamer are introduced.

The hydrodenitrogenation(HDN) performance of the molybdenum carbide catalyst was evaluated by using 5% pyridine/cyclohexane as a model reactant.

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.

Thermoresistant saggers containing silicon carbide and granular filler were produced through slip casting in plaster mould.

Cemented carbides metal: Tungsten powder, carbonize tungsten, Cobalt powder, Molybdenum powder, pure tungsten, Cobalt nickel material, tungsten copper metal, etc.

Although PM has solved the problem of carbide segregation and crassitude fundamentally, it has complicated technics and extortionate cost, so restricts its application.

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%.

The second carbide is dispersed in the matrix which has good plastoelastic retained austenite, also slows up the material loss when the sands erode the surface.

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.
