Jet processing of direct chill cast aluminum ingots
Macrosegregation of solute elements during casting operations has been a subject of observation, discussion, and research for several hundred years. The unique casting conditions found in the Direct-Chill aluminum casting process can lead to significant accumulation and depletion of solute elements …

An Investigation of Improving Wear of 390 Die-cast Aluminum Through Hardcoat Anodizing
… occurs on the surface of a Hardcoat anodized die-cast aluminum surface, which was sliding against a composite rubber belt. This research investigated known wear theories and the results for previous testing to understand the mechanisms that were likely occurring in this application. These theories …

Optimized Surface Roughening by Pulsed Waterjet for Suitable Adhesion Strength of Plasma Transferred Wire Arc Coating
… project is to eliminate the expensive nickel-aluminum pre-bond coat by optimizing the surface roughness profile of the substrate to provide acceptable mechanical bonding between the coating and substrate. In this study, low carbon stainless-steel was plasma spray coated on a range of pulsed …
