It does not build up or become tacky because it contains no solids like Teflon, wax, moly, graphite or plastic.

因为他不含如铁福龙，蜡，钼，石墨或塑胶类的固体物质，是故不会累积或变黏。

Hetian to the mineral composition of tremolite - actinolite-based, and contain trace amounts of diopside, serpentine, graphite, magnetite and so on.

In further treatment with HNO3, the amount of surface oxygenous groups was increased, and the surface polari- ty was transformed from hydrophobic to hydrophilic.

随后的HNO3处理可以使石墨化活性炭表面的含氧基团增加，改变载体的浸润性能，有利于催化剂活性组分的分散及催化活性的提高。

Provided are carbide derived carbon materials prepared by thermochemically reacting carbide compounds and a halogen containing gas and extracting all atoms of the carbide compounds except carbon atoms, wherein the intensity ratios of the graphite G band at 1590 cm -1 to the disordered-induced D band at 1350 cm-1 are in the range of 0.3 through 5 when the carbide derived carbon is analyzed using Raman peak analysis, wherein the BET surface area of the carbide derived carbon is 1000 m 2 /g or more, wherein a weak peak or wide single peak of the graphite (002) surface is seen at 2 = 25 DEG when the carbide derived carbon is analyzed using X-ray diffractometry, and wherein the electron diffraction pattern of the carbide derived carbon is the halo pattern typical of amorphous carbon when the carbide derived carbon is analyzed using electron microscopy.

The experimental results denoted that the finer pearlite along the austenite boundaries in the as-cast Cr30Ni20NRE steel disappeared first under long-term and high-temperature service condition, and that an umber of Cr- richened carbides were formed due to unila-teral carburizing at long-term and high- temperature, consequently causing Ni to concentrate, bulging and calalyzing decomposition of the carburizing gas.

试验结果表明，长期在高温条件下服役，铸态Cr30Ni20NRE耐热钢中沿奥氏体晶界的珠光首先融入奥氏体，长期高温单边渗碳形成大量富铬碳化物，促使镍富集并起泡形成瘤状物，催化含碳气体的分解；表层瘤状物使辐射管表层疏松，表面积扩张，加快了碳向基体的渗入，提供了碳化物持续长大的条件，并引起沿碳化物周边开裂和奥氏体基体严重萎缩；合金元素的重新分布造成主合金元素铬和镍产生两极分化，镍和硅的富集促使石墨化，与侵入的氧形成内部氧化空洞和膨胀疏松，最终导致构件穿孔失效。

Carbon fiber medium copper graphite composites with various carbon fiber contents were prepared by means of powder metallurgy. The dry friction tests of the composites under no current or current density of 20 A/cm 2 were conducted for 50 h under sliding velocity of 15 m/s and load of 4.9 N.
