241 It is shown that the size of carbide will be decreased and rate of spheroidization will e increased with decreased of pearlite piece of original structure.

242 The feature of machining harden steel by means of EHM are: it can utilize the carbide tool to machine the harden steel in engine lathe.

243 Make an experiment in steel melting deoxidizer of silicon carbide and analyse the results.

244 Carbide derived carbon is a new kind of porous skeleton carbon material.

245 Besides (http://Sentencedict.com), calcium carbide can react with nitrogen to generate lime nitrogen for agricultural fertilizer .

246 Our main products are Silicon Carbide, Alumina Ceramic, Tungsten Carbide, and Carbon - Graphite Seal Rings.

247 I plant of the chromium oxide , alumina ceramic coating and has a tungsten carbide metal-resistant coating wear, corrosion resistance, high temperature, and other fine performance.

248 Since the vanadium oxide is softer than vanadium carbide, it is easily reduced to fine particles in the step of mixing by means of a ball mill in raw-material preparation.

249 Elements are manufactured of green silicon carbide that is classed as an excess electron type semiconductor.

250 There are some problems in manufacturing of Semi-finished Product of Cemented Carbide Glass Cutter. It is difficult to shaping and there are always carbon elimination and carburize after sintered.

251 By means of the mercurial barometer and pore size analyzer, the effects of bridged particles on the pore volume distribution in nano-meter cemented carbide powder and its compact were investigated.

252 In order to improve the insulation performance of the ladle covering flux a new type carbide rice husk based ladle covering flux has been developed.

253 A welding paste was designed according to a theoretical formula for carbonous density, and an inexpensive method of joining reaction-bonded silicon carbide ceramics was provided.

254 The hardness of black silicon carbide is greater than fused alumina but less than synthetic diamond.

255 The effects of carbonous density, solid volume loading and silicon carbide particle size distribution on the microstructures and mechanical properties of the welding seams were investigated.

256 The breaking rate of improved carbide tool reduced from 15 % to 1.5 % and carbide tool life increased from 60 pieces to 100 pieces.

257 Because of complex structure, traditional designing methods can not be used to do intensity analysis, stiffness analysis and stress analysis precisely for solid carbide end mill.

258 The shaped silicon carbide fibers were prepared from polycarbosilane by melt spinning, curing treatment and sintering.
