Variation in Exoelectronic Emission during the Machining of Metals,
Abstract
A study of the results of machining metals and alloys is making it necessary to use techniques which are sensitive to the structural state of surface layers. An estimate of the physical and structural state of the surface and its capacity for defect formation, along with an investigation of the energy content in the surface layers which are subjected to deformation, can be carried out by the exoelectronic emission technique. The present article describes this technique's use in studying the influence of planing and turning rates on the surface layer quality of certain structural materials. Thermostimulated exoemission curves for specimens worked on the machines were plotted experimentally. The measurements were taken 2 x 10 to the -5th power mm Hg vacuum with the use of secondary emission multiplication.
