Corrosion caused by corrosive chemical environments leads to reduced reliability, increased safety risks, leaks, and contamination of process fluids. In many cases, the corrosion of metal valves is caused by the removal of the passive oxide layer on the surface due to exposure to acidic and/or chlorinated compounds, and it usually manifests as pitting corrosion. Different metal alloys will re-form their passivated surface oxide layers at different rates, thereby affecting the overall corrosion resistance of the valve. Due to the cost and lead time required to obtain these specialized parts, the use of special alloys in valve manufacturing to reduce corrosion is limited. It has been proven that even in the most corrosive hot acid environments, tantalum metal can rapidly form a surface oxide layer. By applying a tantalum surface layer using our unique tantalum ion thermal evaporation technique, its practicality makes it a more cost-effective option for valves. Advantages of tantalum-nickel surface alloys: Ains’ proprietary vaporized tantalum deposition surface alloying technology enables the creation of an extremely strong, uniform, inert, and corrosion-resistant layer of pure tantalum on existing stainless steel valves and related equipment. Tantalum atoms actually grow into the nickel-based material to form an excess layer, thereby creating an inseparable nanoscale surface layer of pure tantalum. The tantalum alloy surface coating we have developed boasts extremely high corrosion resistance, offering you the latest protection solutions to help you overcome industrial corrosion problems. Tantalum alloy surfaces are uniform, stable, and corrosion-resistant, with a strong bond to the base material. Our products possess the corrosion resistance of tantalum metal along with the hardness of standard materials, allowing them to withstand highly corrosive environments as well as high temperature and pressure conditions; they are an excellent choice for process equipment that requires extreme corrosion resistance. Application fields, key technologies: Ains uses its proprietary vapor-phase tantalum vaporized surface alloying technique, which involves vaporization and diffusion within the heater; thereafter, the material enters the reaction system along with the carrier gas. Tantalum diffuses evenly across the surface of the substrate, where chemical reactions take place. The reduced product, tantalum, deposits on the substrate surface, while the oxidized products are removed from the surface by the carrier gas. Thus, vapor deposition can be carried out independently on both the inner and outer surfaces of the product, resulting in a coating with good coverage and a dense structure. Our patented coating technology offers a wide range of applications – from the inner walls of reaction vessels to screws and nuts. It can handle everything from large-scale mass production to custom-made solutions, handling all such tasks perfectly. Our technology offers high controllability, enabling free adjustment of the coating thickness within the range of 0–200 microns. Our coating features high purity, uniform texture, inertness and corrosion resistance, as well as strong adhesion. The tantalum metal layer is formed by tantalum atoms growing on the surface of the substrate, creating an atomic-scale \"supersurface alloy\".
