在内摩擦测量中发现了矿物油和润滑剂涂层对钢铁亚表层弹性和阻尼性能的影响。在涂油陶瓷中没有观察到这种效应，但在带氢的铁和钢中确实发生了这种效应。在包覆金属中，新的内摩擦峰的形成、屈服应变的增加和拉伸箔滑移线密度的增加都伴随着吸氢的发生，这与充氢金属的情况相似。这一现象的起因是油和润滑剂在催化分解过程中析出氢、氢进入金属以及金属亚表层内的氢位错相互作用。在考虑摩擦接触时，应考虑该层的氢致改性和氢致软化或硬化的可能性。
The change of elastic and damping properties of the subsurface layer of iron and steel due to the coating with mineral oil and lubricants has been found in internal friction measurements. The effects were not observed for oil coated ceramics but did occur for iron and steel charged with hydrogen. In the case of coated metals, the formation of new internal friction peaks, increase in yield strain and increase in density of the slip lines of stretched foils were accompanied by the hydrogen uptake, was similar to the case of hydrogen charged metals. The origin of the phenomena is to be the hydrogen evolution from oil and lubricants at their catalytic decomposition, the hydrogen entry into the metal and the hydrogen-dislocation interaction within the subsurface layer of a metal. The hydrogen-induced modification of this layer and the possibility of hydrogen-induced softening or hardening should be taken into account in consideration of the tribological contacts.
