Abstract: A vertical laser cladding system is particularly effective for the interior surfaces of tube-like structures. The vertical cladding process works from bottom to top, so that previously clad layers form a shelf for subsequent application of cladding powder. This system is also particularly effective for handling double-bore plasticating barrels.

Abstract: A metal alloy is melted in a crucible and ejected from the bottom of the crucible as a descending stream of molten metal. The descending stream is impacted with a plurality of primary inert gas jets surrounding the molten metal stream to produce a plume of atomized molten metal droplets. An inert gas is blown onto a lower portion of the plume with a plurality of auxiliary inert gas jets to deflect the plume into a more restricted pattern of high droplet density, thereby substantially eliminating unwanted overspray and resulting wasted material. The plume is projected onto a moving substrate to form a monolithic metallic product having generally parallel sides.

Abstract: An article having a radiation cured coating is formed by:(a) applying to a substrate a first layer of pigmented or unpigmented radiation curable material containing glitter particles such as metallic particles or synthetic glitter particles;(b) applying a second layer of unpigmented radiation curable material over the first layer, and(c) curing the first and second layers with ionizing irradiation or ultraviolet light, either in two steps or in a single curing step after both layers have been applied.

Abstract: An article having an opaque, pigmented, radiation cured coating is formed by:(a) applying to a substrate a thin layer of pigmented radiation curable material and partially curing same with ionizing irradiation or ultraviolet light in an oxygen containing atmosphere; and(b) then applying a second layer of unpigmented radiation curable material over the partially cured first layer and completely curing both the first and second layers with ionizing irradiation or ultraviolet light in an inert atmosphere.
