Effect of WC Concentration on Abrasive Wear Properties of the Thermally Sprayed WC -Ni Coatings
In this work the effects of WC concentration on abrasive wear behavior by thermally sprayed WC coating was evaluated using three body abrasive wear tester. A different combination of WC and NI coatings were deposited on steel substrates by flame spraying using powder with different WC concentrations (0 %, 12.5 %, 25 %, and 50 %). Flame torch was used for heating and coating of process. Microstr...
متن کاملEffect 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...

15 صفحه اولINFLUENCE OF HEAT TREATMENT PARAMETERS,TEMPERATURE AND TIME, ON WEAR AND MICROHARDNESS OF NICRBSI FLAME SPRAYED COATINGS APPLIED ON CK45 SUBSTRATES
The objectives of this research were to find an economical way of reducing porosities in the microstructure of coatings deposited by flame spraying technique on CK45 steel and also trying to increase their cohesive strength to the substrate, so that the overall wear properties of this type of coating can be improved. So several specimens from this steel coated with NiCrBSi powder under specific...
متن کاملTHE 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...
