The influences of several technical factors including material and cleaning condition of can, outgassed conditions of canned powder, size of as-HIPed compact, particle size distributions of powder and HIPing temperature on the qualities of as-HIPed FGH95 alloy compacts were studied in this paper.

FGH95合金;工艺因素;热等静压;本文研究了若干工艺因素:包套材质及其表面清理情况、包套内粉末的除气条件、热等静压锭坯尺寸及所用的粉末粒度组成和热等静压温度对FGH95合金压坯质量的影响。

Methane adsorbed on the Mn〓O〓-Na〓WO〓/SiO〓 catalyst can not be found, but it can be adsorbed on outgassed silica at 173K. Such adsorption is formed by interaction of the adsorbed methane with O〓〓 sites and hydroxyls on the surface. The appearance of the band at 2904cm〓 of the V〓 mode (sym. stretch.), which is an infrared forbidden vibration, implies that the Td symmetry of the methane molecule may be distorted somewhat on the surface of silica. The small frequency shift (30cm〓) of OH stretching indicates that only a weak hydrogen-bonding interaction between adsorbed methane and hydroxyls exists in the methane adsorption.

甲烷不能在Mn2O3-Na2WO4/SiO2催化剂上吸附但在l73K的温度条件下可吸附于SiO〓表面上,这种吸附是通过吸附甲烷与表面配位不饱和氧和表面羟基作用而形成的,红外禁阻的V〓振动模式显示出红外活性说明甲烷分子的Td对称性发生畸变,甲烷吸附后羟基位移只有30cm〓,吸附甲烷同表面羟基间的氢键作用很弱。
