Temperature-Dependence of Hardness and Wear Resistance of Stellite Alloys
A group of Stellite alloys are studied in consideration of temperature effects on their hardness and wear resistance. The hardness test is conducted on a micro-hardness tester with a hot stage equipped that allows heating the specimen up to 650°C. The wear resistance of each alloy is evaluated using a pin-on-disc tribometer with a heating furnace built-in that provides the temperature capacity ...
متن کاملTribo-Mechanical Evaluations of Cobalt-Based (Stellite 4) Alloys Manufactured via HIPing and Casting
(HIPing), can improve the tribo-mechanical properties of cobalt-based alloys. The alloy selected for this investigation had a nominal wt.% composition of Co-30Cr-14W-1C, which is similar to the composition of the commercially available Stellite®4 alloy. The Hot Isostatic Pressed (HIPed) alloy had a much finer microstructure than the cast alloy, which showed a typical hypoeutectic dendritic micr...
متن کاملTHERMAL FATIGUE RESISTANCES OF 356 AND 413 CAST Al ALLOYS
Abstract: Thermal fatigue is a stochastic process often showing considerable scatter even in controlled environments. Due to complexity of thermal fatigue, there is no a complete analytical solution for predicting the effect of this property on the life of various components, subjected to severe thermal fluctuations. Among these components, one can mention car cylinder, cylinder head and pi...
متن کاملEvaluating abrasive wear of amorphous alloys using nanoscratch technique
The hardness and elastic modulus of several Zr, Pd, Cu, and La-based amorphous alloys were investigated using nanoindentation. Abrasive wear of these alloys was also evaluated and compared using nanoscratch techniques under a ramping load. Damage caused by scratching was examined using SEM. Material pile-up took place in all scratched samples, but to different degrees. The scratched surface was...
متن کاملDeffects in Dental Alloys Cast Single Tooth Restorations
Casting failures of alloys in dental technology should be the exception, not the rule. They have to be detected in time and associated with possible causes. For the experimental part base metal alloys single tooth restorations were achieved using the conventional lost wax process for casting in order to be evaluated. Some casting defects obtained during the experimental part are exemplified: in...
