Thermal spray applications introduction
Thermal spray applications include almost all of the industrial production sector, in addition to the previously described in the automotive and mold industry and the well-known in the aviation, navigation, textile, machinery and other applications, but also quickly expanded to other areas. Such as spraying aluminum for oil piping welds and spraying abrasion-resistant coatings on oil equipment valves, overflow stoppers and drillstring tools; spraying carbonyl apatite on artificial joints to enhance titanium substrate and organic Biocompatibility; spraying a ceramic coating on a printing roller and engraving the lines with a laser for drawing the ink from the ink pool to the printing chamber and spraying the steel on the aluminum valve stem cap of the air conditioning compressor to To achieve the purpose of weight loss and wear, and so on.

Titanium carbonitride powder Product use
Titanium carbonitride has the advantages of TiC and TiN, and has the characteristics of high melting point, high hardness, wear resistance, oxidation resistance, corrosion resistance and has good thermal conductivity, electrical conductivity and chemical stability, widely used in cutting tools, Powder metallurgy and metal ceramic products. Titanium carbonitride made of cermet has the following characteristics: hardness (HRA) up to 91-95, you can reach the hardness of non-metallic ceramic tool level; have a good wear resistance and the ideal resistance to crescent crater wear capacity.

Advantages and disadvantages of high – speed gas spraying technology and its use
The most prominent advantage of high-speed gas spraying is the ability to spray high-quality tungsten carbide coatings. Coating is dense, high bonding strength, low oxide content. It is used in aviation and space technology, pumps and compressor shafts, valves, sealing surfaces, papermaking rollers, and petrochemical industries where wear and corrosion resistance is required. HVOF has higher bonding strength, lower oxide content, better abrasion resistance and higher deposition rate than plasma coating. The coating can be thicker due to lower internal stress in the coating. And HVOF spraying the need to control the parameters of only half of the plasma spray, so the spray is simple, good quality coating repeatability.Due to the low temperature of HVOF, it is generally not suitable for the spraying of ceramic materials. However, some spray guns (such as Top Gun, HV-2000) have a high heating capacity, can be very dense ceramic coating.
Economic Effect of Arc Spraying Mold
(2) arc spraying mold making die short cycle. Conventional mold processing From casting (or forging), roughing, finishing, profiling, fitter to the mold finished product, you need a very long processing cycle, some of the complex shape of the cavity mold, the direct processing of forming more Difficulty, have to use mosaic mosaic structure, so that the mold design and manufacturing cycle corresponding lengthened. Arc spraying production of molds, as long as the sample can be produced in a very short period of time to meet the requirements of the mold. Production of a projection area of ??1900mm × 1200mm, three-dimensional decorative surface patterns and plastic wood double bed head mold, only 1 week time. The same size of a mold, if the use of conventional methods of cast aluminum processing, produced more than 5 months to complete.
Coated tools
Tool coating technology since its inception, the improvement of tool performance and processing technology plays an important role in the progress of technology, coating technology will be coated with a layer of traditional tool coating, the tool performance has undergone tremendous changes. The main coating materials are: Tic, TiN, Ti (C, N), TiALN, ALTiN and so on. Coating technology has been applied to endmills, reamers, drill bits, composite hole processing tools, gear hobs, shaper cutters, shaving cutter, forming broaches and a variety of machine-indexable inserts blade to meet the high-speed machining Strength, high hardness Cast iron (steel), forged steel, stainless steel, titanium alloy, nickel alloy, magnesium alloy, aluminum alloy, powder metallurgy, nonmetal and other materials production technology different requirements.
