Application of Powder Spraying in Surface Treatment of Aluminum Profiles
3 significantly reduced energy consumption, ordinary anodizing, electrophoretic coating production process, the consumption of water and electricity is quite large, especially in the oxidation process. Rectifier output current up to 8000 ~ 11000A between the voltage of 15 ~ 17.5V, coupled with the heat consumption of the machine itself, you need to constantly use recycled water to cool, the power consumption is often about 1000 tons, At the same time reduce the auxiliary facilities can also reduce some power consumption;
Flame spray
Flame spray Conventional flame spraying is the use of flammable gas combustion flame as a heat source, the spray material heated to melt and spray onto the substrate surface to form a coating. Now, for the flame spraying process, equipment development, and constantly develop a new flame spraying method. High speed oxygen fuel spraying (HVOF) is a major technical field of flame spraying. This process was developed by Union Carbide Corporation early, and in 1953 invented the oxygen-acetylene fuel D-Gun system. Followed by the use of oxygen – propane, oxygen – propylene oxide – hydrogen as fuel JetKote, TopGun, CDS, so that the technology level of this process has been continuously improved. At present, PRAXAIR company has launched JetStar high-speed air fuel spraying technology and high-speed burning wire spray gun. It uses fuels as liquid fuels such as kerosene, diesel, etc ; combustion supplies are industrial compressed air and use it to cool the gun, avoiding many HVOF guns for additional cooling requirements, reducing operating costs. The JetStar system uses 19 L / h of liquid fuel and 4 m  3 / min of compressed air at a cost of only $ 7 per hour while using oxygen-kerosene at...
Thermal spray applications-Mold
Thermal spray applications-Mold At present, the thermal spray application research is more rapid prototyping technology. This is a hot spray metal materials or welding metal to produce the entire parts of the technology, the spraying process is mainly arc spraying. The process can be obtained in any shape of the parts, so some people even think that "rapid prototyping will lead to the next material revolution." SULZERMETCO has studied more about this technology and has been used in actual production. Over the past three years, SULZERMETCO has used this technology to produce more than 100 horizontal turbo buckets for its customers. The United Kingdom Nottingham has been patented for rapid tooling for Spray Molding Development, which is used to make steel molds and production tools by spraying molten metal into a low cost, accurate aluminum refractory On the sample. The tooling produced in this way over the past two years has been extensively tested by several large companies, and plastic molds and metal forming processes all show great performance. The first batch of production tooling was made in September 1996 in the United Kingdom, these tooling is expected to produce more than 1 million parts. At a recent demonstration of...
TiC-based cemented carbide Features(二)
c. TiC-based inserts surface to form a coating structure Mo2C, can improve its wetting with the steel matrix, through the quenching, the alloy steel matrix into martensite and a small amount of retained austenite, alloy The hardness and strength are greatly improved. Alloy cast in the high manganese steel castings, after water toughness can improve its strength and toughness.
Titanium carbide nitride powder
Titanium carbide nitride powder purity 99%, zero-dimensional ternary structure, titanium carbide and tin, titanium carbide nitride powder is more suitable for welding materials, can improve the wear resistance, used in spraying materials as additives in a rigid tool.
Arc Spraying Technology
Arc Spraying Technology In the 1980s, the arc spraying technology of some industrial developed countries such as the United States and Germany has been greatly developed, and the quality of coating has been greatly improved, which has promoted the extensive application of arc spraying technology in industry. At present, the arc spraying technology in the country has been the attention of many departments, is being more and more widely used. Arc spraying technology can be applied to corrosion, wear, decoration and the formation of special functional coatings and other fields, especially in the field of corrosion, arc spraying is the most effective and most economical long-term anti-corrosion technology. Compared with other coating technology, arc spraying technology has the advantages of good coating quality, small workpiece deformation, high production efficiency, high energy efficiency, good economic efficiency, simple operation and easy field operation.
