METHODS OF CONTROLLABLE INTERNAL RUPTURE IN SOLIDS AND LIQUIDS FOR OBTAINING ATOMICALLY-CLEAN SURFACES AND INVESTIGATING THEIR ADHESION

摘要

Controllable internal rupture (CIR) methods for obtaining atomically-clean solid surfaces and closed ultrahigh vacuum (UHV) space are described. A number of modifications of CIR methods have been developed. Their performance, characteristics and applications for investigation of adhesion are considered. CIR methods are based on the creation of virgin atomically-clean rupture surfaces in the bulk of solids during deformation of specially manufactured heterogeneous systems. For all modifications of the method, the samples have been manufactured in the form of vacuum-fight capsules and the investigation procedure has been carried out in atmospheric conditions. CIR methods, in addition to well-known UHV methods, offer a broadening of the research opportunity and simplification of the experimental equipment as well as offering maintenance of surface cleanliness for a long time (up to some months).
