Materials Processing Technologies

Review from Ringgold Inc., ProtoView: Over 350 papers explore manufacturing from perspectives of casting, forming and machining, additive processing and joining technologies, the evolution of material properties in manufacturing processes, the engineering or degradation of surfaces, and the design and behavior of equipment and tools. The topics include the temperature gradient and heat conduction of titanium alloy during laser welding, the microstructure and properties of non-electric welding joints, fabricating iron based amorphous composite coatings on an aluminum substrate by electrothermal explosion spraying, bursting behavior in a hydroforming double-cone tube, the high quality fiber laser cutting of electronic alumina ceramics, analyzing the mechanical behavior of laser cladding under repeated impacting load, chromium-free color passivation for zinc coating treated with silicate, design methodology and concurrent engineering on a scroll vacuum pump, and focusing the spot shape of high-power carbon dioxide lasers.
