Evaluation of Microstructure and Wear Behavior of Iron-based Hard - facing Coatings on the Mo40 Steel
Mo40 low-alloy steels are mostly used to produce industrial components such as crane wheels which are exposed to abrasive wear. However, during working conditions, their wear resistance is reduced after a while due to its low hardness. With increasing abrasive wear, the dimensions of components decrease and they need to be repaired for surface modification. In this regard, hard overlay coatings...

متن کاملSilica-clad crystalline germanium core optical fibers.
Silica-clad optical fibers comprising a core of crystalline germanium were drawn using a molten core technique. With respect to previous fibers drawn using a borosilicate cladding, the present fibers exhibit negligible oxygen despite being fabricated at more than twice the melting point of the germanium. The counterintuitive result of less oxygen when the fiber is drawn at a higher temperatures...
متن کاملPolarization characteristics of double-clad elliptical fibers.
A scalar variational analysis based on a Gaussian approximation of the fundamental mode of a double-clad elliptical fiber with a depressed inner cladding is studied. The polarization properties and graphic results are presented; they are given in terms of three parameters: the ratio of the major axis to the minor axis of the core, the ratio of the inner cladding major axis to the core major axi...
متن کاملIce 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...
