Cold Spray is a hard-edged solid skills. This approach will be accelerated solid particles ultrasonic kinetic energy into thermal energy upon impact to the outer plating, and then the end of the welding metallurgy. The principle of this skill is: each metal has a specific, temperature-dependent critical particle velocity, when the particle motion will exceed the rate that is welded to the top of the plating. In conventional thermal spraying skills, due to higher temperatures, coating and plating information it will be oxidized to produce metallurgical deformation and the remaining tensile stress. Conversely, the cold spray coating made of skills, the porosity is low (<0.5%), and oxidation, anti-phase transformation, a variety of metals, cermets or combinations of other materials can reduce the tensile stress. In the high-pressure cold spray skills, high pressure helium or nitrogen (350 to 450 pounds / square inch) as a carrier gas, spray data can accelerate to supersonic speeds. The gas is heated and forced through a gathering - divergent nozzle (deLaval) spraying process, where it is accelerated to supersonic speeds (greater than 1000 m / sec). Spraying particles are written in the upstream side of the nozzle in the axial direction. ① common noun paint powder coating: powdered paint solvent-free. ② paint: a class containing a pigment coating, when applied to the substrate, to form an opaque film having a protective, decorative or special properties. ③ multi-component coating: packaging of several components, the coating must be mixed according to a predetermined ratio prior to use. ④ resin: one solid, semi-solid or pseudo-solid, the molecular weight of the polymer uncertain, sometimes it can be a liquid polymer. Usually soften or melt temperature range. ⑤ pigment: usually a powder, insoluble in the medium of colored material, because of its optical, protection, decoration and other properties used in the coatings. ⑥ packing: also known as a pigment material, usually white or slightly colored, a refractive index of less than 1.7 thermal sprayed pigments, due to its physical or chemical properties for use in coatings. ⑦ curing agent: a compound having a co-catalytic or reactive with. ⑧ Thinner: Single - or volatile liquid component is added to reduce the viscosity of the coating. ⑨ Solvent: under normal dry conditions volatile, and can be one-component or multi-component liquid complete dissolution of the binder. ⑩ coating: After a continuous film thus obtained was applied. ? Film (film): continuous film coated on a substrate or coat formed. ? Varnish: a class-free paint coloring matter. Applied to the substrate, and forms a transparent film having a protective, decorative or special properties. ? Blending paint: one component contains more pigment (or filler) paint. Film hard, flat spray, but the degree of detail and weathering less the same series enamel. Cheap for ordinary wood, metal surface coating. ? Enamel: one capable of forming a film of a very bright paint. Film appearance such as ceramic or enamel, surface smooth, delicate, hard, with decorative sense. There are a half, semi-gloss, matt of the other, bright shiny enamel paint, enamel and matte pastel colors, with different decorative sense.
