What is the formation of a spray?

Creating a spray

is a process of forming a metal that spews a molten, atomized metal on a rotating substrate to form a metal ingot or sculpture. The high level of solidification of the process leads to a well -defined microstructure. The process produces a material similar to the material achieved by powder metallurgy for a fraction of the cost. Depending on the shape of the substrate, groups or rods of different shapes are possible. This process refers to a wide range of alloys. Modern tools and tools require metal parts that fit firmly and move smoothly. In addition, these precise parts must show high strength and hardness, the function of a solid metal microstructure. For example, carbides, carbon metal compounds are an important factor in the final hardness of steel used in highly stressful environments, such as in space or underwater. In microscopic examination of cast steel leaves, carbide crystals are perceived as long chains, which increasesis the fragility of the final product. Most of these carbides are chrome compounds. In similar steel leaves created by spray, carbides are smaller, evenly distributed and are vanado compounds, stronger metal.

Forming

Spray is cheaper than metallurgy powder. In this alternative technology, the powder is first prepared from one of several techniques. Then the powder is mixed, compacted in the matrix and salt in the furnace. Sintering allows a slow coalescence of particles when it melts and runs together. Grain growth is microscopic. Powder metallurgy Products very dense, strong materials.

Products

spray products are also very dense, but require two steps of processing. The alloy is melted, atomized by a nozzle and affects the substrate. Cooling the nitrogen gas, which is a blown anti -sealing current to the droplets, the droplets are maintained separate and different but faster. Metal segregationThe alloys are delayed by not allowing the droplets to mix. The droplets are partially molten when they hit the substrate; In powder metallurgy, metal is in the form of solid particles.

The

spray forming process has been refined as the Osprey process, a methodology for commercial methodology for high -strength steel. The process variation, the Spraycast-X ™ process allows nickel alloys to produce nickel-based alloy for parts of the gas turbine engine. The costs are also reduced because less waste metal must be removed to form the last part.
