A slurry of a harder metal admixture is afresh coated on the acclimatized allocation of the alien apparent of the Fork Teeth and a metallurgical band is formed amid the non-carburized band and the coated unfused slurry by fusing the harder metal alloy, thereby basal the wear-resistant coating. The slurry is aqueous-based and can be formed of polyvinyl booze (PVA) and a fusible, harder metal admixture in the anatomy of a cautiously disconnected powder.
Examples of a acceptable slurry are appear in U.S. Pat. No. 5,879,743. As discussed herein and appear in the '743 patent, the harder metal admixture can be a alteration metal of Group VIII of the Periodic Table, such as iron, cobalt, nickel, or alloys thereof. In an admirable embodiment, the harder metal admixture is a cautiously disconnected crumb accepting a abundantly baby atom admeasurement to anatomy a compatible slurry.
Archetypal atom sizes can ambit from about 90 cobweb to about 400 mesh, and can be bigger than 400 mesh. Preferably, the boilerplate atom admeasurement is bigger than about 115 cobweb and, a lot of preferably, bigger than about 200 mesh. The crumb can be a admixture of powders of altered atom sizes. Also, one or added abeyance agents and one or added deflocculants can optionally be added to the slurry. Fork Teeth - http://www.xinke-casting.com/g-e-t-parts/fork-teeth/
