ICE ADHESION STUDIES: PROPERTIES OF DEFECTS IN THE INTERFACIAL REGION
CONSIDERABLE WORK HAS BEEN DONE ON THE SURFACE CHEMICAL ASPECTS OF ICE ADHESION. ANOTHER POINT OF VIEW, HOWEVER, IS THAT ICE ADHESION MAY BE PRIMARILY A FUNCTION OF THE STRENGTH OF ICE IN THE INTERFACIAL REGION; I.E., ICE SHEARED FROM A SURFACE BREAKS AWAY COHESIVELY IN THE ICE RATHER THAN ADHESIVELY AT THE SUBSTRATE. THE PROPERTIES OF ICE IN THE INTERFACIAL REGION, ESPECIALLY THOSE FACTORS THAT INFLUENCE THE STRENGTH OF ICE (POINT AND LINE DEFECTS), HAVE BEEN INVESTIGATED THIS PAST YEAR. INVESTIGATIONS, INCLUDED BERG-BARRETT AND LANG X-RAY TOPOGRAPHY, HAVE REVEALED LINE DEFECTS IN ICE TO BE CHARGED. THE PRESENCE OF THIS CHARGE IS CONSIDERED IN THE DEVISING OF METHODS TO WEAKEN ICE IN THIS REGION. OTHER STUDIES INCLUDE SURFACE SELF-DIFFUSION, EFFECTS OF ICE-WEAKENING IMPURITIES SUCH AS HYDROFLUORIC ACID, AND MICROHARDNESS INVESTIGATIONS TO DETERMINE THE EFFECTS ON ICE DISLOCATION MOBILITY AFTER THE USE OF ICE-RELEASE AGENTS. /AUTHOR/
