Langues : Américain (ame) Catégories : Borure de tungstène Revêtement métallique Soudage par gaz inerte de tungstène Index. décimale : 667.9 Revêtements et enduits Résumé : Tungsten boride (WB) powder was used as a wear-resistance material, then clad on a Ti–6Al–4V substrate by the gas tungsten arc welding (GTAW) method. The titanium boride (TiB) reinforcing phase was formed in situ in the clad layer during the cladding process. Since the TiB and tungsten (W) reinforcing phase exist in the clad layer, the hardness of the clad layer is double that of the substrate. Wear test results reveal that the tribological performance of the WB-clad layer is superior to that of the Ti–6Al–4V substrate. This investigation also discusses the forming mechanism of the clad layer microstructure.

The effect of hydrogen shielding gas on microstructure and abrasive wear behavior in the surface modification process using the tungsten inert gas method / V. V. Cay in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 8, N° 1 (01/2011)  

[article]  inJOURNAL OF COATINGS TECHNOLOGY AND RESEARCH > Vol. 8, N° 1 (01/2011) . - p. 97-105 Titre : The effect of hydrogen shielding gas on microstructure and abrasive wear behavior in the surface modification process using the tungsten inert gas method Type de document : texte imprimé Auteurs : V. V. Cay, Auteur ; S. Ozan, Auteur ; M. S. Gök, Auteur Année de publication : 2011 Article en page(s) : p. 97-105 Note générale : Bibliogr. Langues : Américain (ame) Catégories : Alliages Hydrogène Métaux -- Surfaces Microstructures Revêtements:Peinture Soudage par gaz inerte de tungstène Index. décimale : 667.9 Revêtements et enduits Résumé : In this study, SAE 1020 steel surfaces were separately alloyed with preplaced high-carbon ferro-chromium (FeCr), ferro-molybdenum (FeMo), and ferro-titanium (FeTi) powders by using a tungsten inert gas (TIG) heat source. By using two different types of shielding gas compositions during the alloying process, the study investigated the effects of modified shielding gas composition on the microstructure, hardness, and abrasive wear resistance of specimens. It was observed that with modifications in shielding gas composition, the microstructure and volume hardness of the specimens changed and no cracks and voids were formed in the interface area. The X-ray examinations of the specimens identified Fe, FeTi, and FeMo phases in their microstructure as the first phase, and Cr7C3, Fe3C, Fe7C3, and TiC phases as the second phase. As a result, it was concluded that changes in shielding gas composition in surface alloying process significantly affect specimens’ microstructure and mechanical properties.
