Hydrophobic films and their efficiency against moisture transfer. 1. Influence of the film preparation technique
The aims are to study the influence of the technique used in the preparation of hydrophobic films on their efficiency against moisture and to determine factors that influence their barrier properties. For dipped films the influence of thickness and the water vapor pressure differential across the film were also studied
Research methods based on recording parameters of electrical conductivity are considered for future application in nanotribology. Design relationships of conductivity are presented for idealized models of interface under conditions of boundary lubrication; contributions of various conductivity types in the total contact conductivity are estimated. An application methodology is described for the methods to study the properties of boundary lubricating layers. Some of the results obtained from the study of strength and frictional properties of boundary lubricating nanometre layers under normal load and sliding conditions are discussed.
