Ice Abrasion Tests of Metal Based Coatings
Ice abrasion tests were carried out to evaluate the wear resistance of a number of metallic coatings suggested for use on the Molikpaq in the ice zone during its deployment offshore of Sakhalin Island in the 1990’s. At this site, the structure would be exposed to actively drifting ice for about six months each year during which time the structure would be potentially exposed to extensive ice ab...
متن کاملA review on the physics of ice surface friction and the development of ice
Our walking and running movement patterns require friction between shoes and ground. The surface of ice is characterized by low friction in several naturally occurring conditions, and compromises our typical locomotion pattern. Ice skates take advantage of this slippery nature of ice; the first ice skates were made more than 4,000 years ago, and afforded the development of a very efficient form...
متن کاملIce internal friction: standard theoretical perspectives on friction codified, adapted for the unusual rheology of ice, and unified
Sea ice contains flaws including frictional contacts. We aim to describe quantitatively the mechanics of those contacts, providing local physics for geophysical models. With a focus on the internal friction of ice, we review standard micro-mechanical models of friction. The solid’s deformation under normal load may be ductile or elastic. The shear failure of the contact may be by ductile flow, ...
متن کاملProduction of Ice Nucleation Deficient (Ice-) Mutants of the Epiphytic Strains of Erwinia herbicola
To mutate the Ice Nucleation Active (INA) gene in Erwinia herbicola strains, Tn-5 transposon carried by Psup2021 plasmid was used. This plasmid was transferred to the bacterial cells by electroporation. Electrotransformation was carried out for 2.5 ms at 1800 v and 1 mm distance between the electrodes. Polymerase chain reaction was used for determination of presence or loss of INA gene, using a...
متن کاملIce friction in speed skating: can klapskates reduce ice frictional loss?
PURPOSE Reducing ice friction was one of the motives for developing the klapskate. However, the magnitude of power dissipation that occurs with conventional skates when a skater plantar flexes his ankle and the tip of the blade is pressed into the ice has not been quantified previously. In this study, we examine how ice friction varies during a single stroke with conventional skates and estimat...
