INFLUENCE 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...

15 صفحه اولFormation Mechanism of Silicon Modified Aluminide Coating on a Ni-Base Superalloy
Formation mechanism of silicon modified aluminide coating applied on a nickel base super alloy IN-738 LC by pack cementation process was the subject of investigation in this research. Study of the microstructure and compositions of the coating was carried out, using optical and scanning electron microscopes, EDS and X-ray diffraction (XRD) techniques. The results showed that due to low partial ...
