碳化

Description :The new Tungsten based IF material has up to twice thestrength of the best impact resistant materials currently used inprotective armor applications such as boron carbide and siliconcarbide, and are over 5 times stronger than steel.

描述：基於IF 材料的新钨比现有使用的保护装甲材料如碳化硼和金刚砂拥有两倍的最好冲撞抵抗效果，是钢强度的五倍以上。

According to this point it has good ability to absorb neutron and resist eradiation.Because of their high hardness and strength, excellent wear and corrosion, low density, low friction coefficient good self-lubricate and high temperature properties both silicon carbide and boron carbide components have been widely used in many industries.

由于碳化硼中的B14中子缺失，它还具有较大的热中子俘获截面，具有极好的中子吸收和抗辐射性能，由于其具有耐高温，耐酸碱腐蚀，高强度，高化学稳定性，比重轻，半导体等特点而成为众多行业的首选材料。

If it could stand up to higher energy threats, military experts believe that boron carbide - whose hardness approaches that of diamond - would find greater use as a lightweight armour material for military, police, diplomatic and other vehicles.

因为如果该材料能抵抗高强度武器的话，碳化硼这种和钻石硬度相当的材料能够成为军事车辆、警车、外交车辆和其它车辆的轻型防护材料。

The mostly products in the interface are AbBC which grows along the boron carbide and the boron carbide are attacked by the aluminum.

界面反应的主要产物为Al_3BC，碳化硼被铝侵蚀的同时，Al_3BC等反应产物生成。

Production of small special-shaped wheel specifications, high-precision Whetstone, boron carbide, natural jade, agate, rubies, and so I plant "high-quality products."

生产的小规格异型砂轮、高精度油石、碳化硼、天然玉、玛瑙、红宝石等为我厂"拳头产品"。

For a certain hot-pressing conditions, relative density, flexural strength and fracture toughness of the materials hot-pressed from boron carbide powder with 7wt%carbon are 98.5%, 460 MPa and 7.65 MPa*m1／2,respectively.

结果表明：在一定的热压条件下，添加7％C的碳化硼烧结体的相对密度可高达98.5％，断裂韧性为7.65 MPa*m1／2，弯曲强度仍能达460 MPa。

The development and research status of boron carbides for the Bulletproof Ceramic were summarized in this article.

The carbonated tree in volcanic breccia has been studied through high resolution transmission electronic microscopy,X-ray powder diffraction and laser Raman spectroscopy.

对浙江温岭火山角砾岩中的碳化树木进行了高分辨电子显微镜、X粉晶衍射和激光拉曼光谱研究。

The wall of the burning chamber was pitted at the beginning then gradually burnt through.By means of the Bunsen burner,tubular furnace and XRD,SEM,EDS,this special type of high-temperabure destruction was studied.It was found that the phenomenon is resulted from the combined action of CO and lower hydrocarbon on Ni-Cr alloy.Firstly,Ni-Cr alloy is carbonized and selectively oxidized by CO to produce Cr2C,Cr3C2 and Ni-Cr2O3,while the capillary cracks in the surface layer are formed simultaneously.

作者利用几种现代手段和试验方法，对这一燃烧破坏现象进行了系统地模拟研究，发现这是CO和低分子烃在高温下对合金共同作用的结果：第一步CO作用使合金表层发生氧化和碳化，造成裂隙；第二步低分子烃扩散进裂隙并在Ni-Cr2O3微粒的催化下，裂解生在石墨炭并包复在Ni-Cr2O3微粒周围，体积增大。
