Effect of Abrasive Size on Wear

THE EFFECT OF HEAT TREATMENT ON ABRASIVE WEAR RESISTANCE OF Fe-34Cr-4.5C%WT HARDFACING ALLOY

Abstract: Hardfacing is one of the most useful and economical ways to increase the service life of components subjected to abrasive wear. Iron based hardfacing alloys have long been considered as candidate coatings for wear-resistant applications in industry. In the present work two layer of Fe-34Cr-4.5C%wt hardfacing alloy was deposited on ASTM A36 carbon steel plates by SMAW method. The m...

Effect of Abrasive Particle Size on Abrasive Wear Resistance in Otomotive Steels

If one of the surfaces which are in touch is rough and hard, it chips the other surface due to relative motion or touching forces. The wear is called two-body abrasive wear. If there are free abrasive particles between the two bodies, the wear is called three-body abrasive wear. The free abrasive particles may be external material dust or the remains of chipping. Usually, the wear starts as a t...

Effect of Carbide Particle Size on the Microstructure, Mechanical properties, and Wear Behavior of HVOF-sprayed WC-17% Co Coatings

This study investigates the effect of carbide particle size on the microstructure, mechanical properties, and abrasive wear resistance of WC-17%Co HVOF-sprayed coatings. The characteristics of WC-1, WC-2, and WC-3 coatings with carbide sizes of 1 µm, 0.9 µm, and 0.5 µm, respectively, were also investigated. WC-1 coating experienced the maximum carbon loss of 42%, while WC-2 and WC-3 coatings un...
