Black gold steel nano infiltration technology
Black gold steel nano infiltration technology, is through a variety of elements infiltrated into the surface of the metal to form a composite infiltration layer, so as to achieve the purpose of making the surface of the parts modified. It is not hardened, but achieves the effect of surface hardening. The latest improved process is called black gold steel nano infiltration technology. Its advantages over the traditional surface treatment industry is that no deformation, higher hardness, deeper blind holes, neutral salt spray test up to 800 hours or more, high efficiency, no need to polish the surface of the substrate can also achieve the corresponding degree of finish, can be applied to non-standard and large and small parts.
Introduction:
Black gold steel nano-penetration treatment: technology will be heat treatment and anti-corrosion treatment is completed at a time, the treatment temperature is high, the time is short, and can simultaneously improve the surface hardness of the parts, neutral salt spray test, abrasion resistance and corrosion resistance, strong abrasion resistance, deformation of a small, non-polluting. It has the advantages of optimizing the processing procedures, shortening the production cycle and reducing the production cost, and has been recognized and praised by many manufacturers.
Black gold steel nano infiltration layer treatment technology in the process is a combination of heat treatment technology and anti-corrosion technology, in the performance of high wear resistance and high corrosion resistance, in the infiltration layer is a composite infiltration layer composed of a variety of compounds. Therefore, foreign countries believe that this is a great progress in the field of metal surface strengthening technology, call it a new metallurgical method.

Features:
At present, the black gold steel nano-penetration technology in the country has also been a large number of popularization and application, especially in automobiles, motorcycles, textile machines, machine tools, electrical switches, molds and dies on the use of the effect is very prominent. Its specific features are as follows:
1 Good wear resistance, fatigue resistance
The process can greatly improve the surface hardness and wear resistance of various ferrous metal parts, reduce the coefficient of friction. After the products are treated with black gold steel nano-penetration technology, the wear resistance is more than 20 times higher than that of conventional quenching and high-frequency quenching, more than 12 times higher than that of carburizing quenching of 20# steel, and more than 4 times higher than that of hard chrome plating and ion nitriding.
Fatigue test shows that: the process can make the fatigue strength of medium carbon steel increased by more than 60%, than ion nitriding, gas nitriding effect are good. The process is especially suitable for parts with complex shapes, solving the technical key to the deformation problem.
2 good corrosion resistance
On several different materials, different processes to deal with the sample according to the same test conditions, according to the ASTMBll7 standard for continuous spray test, salt spray test temperature 35 ± 2 ℃, relative humidity & gt; 95%, 5% NaCL aqueous solution spray. The test results show that the corrosion resistance of the parts treated with black gold steel nano infiltration technology is 5 times that of 1Crl8Ni9Ti stainless steel, 8 times that of chromium plating, 20 times that of blackening, and the neutral salt spray test reaches more than 800 hours, which can fully meet the needs of extreme customers.
3 Small deformation after product treatment
Workpiece by the black gold steel nano-penetration technology, almost no deformation, can effectively solve the hardening deformation problems that are difficult to solve the conventional heat treatment methods. For example: the size of 510 × 460 × 1.5mm carbon steel plate by black gold steel nano-bursting technology after treatment, the surface HV ≥ 1000, the unevenness is less than 0.4mm. At present, the black gold steel nano-bursting technology in the many shaft parts, long and thin rod on the application of a very successful, effective solution to the existence of heat treatment has been hardening and product deformation of the contradiction.
4 can replace multiple heat treatment processes and anti-corrosion treatment processes, short cycle time
Workpiece by the black gold steel nano-penetration technology, after treatment, in order to improve its hardness and abrasion resistance on the basis of improving its corrosion resistance, and the formation of a black, beautiful appearance, can be used to replace the conventional quenching a tempering a black (chrome) and other processes, shorten the cycle time, reduce production costs. Cost reduction. A large number of production data show that the black gold steel nano-penetration technology treatment and carburizing quenching compared to energy saving 70%, than the hard chrome plating cost savings of 50%, cost-effective.
5 high level of non-pollution, no environmental pollution
It is well known that most of the metal surface treatment processes are incidental to the production of a large number of toxic and harmful chemicals. Electroplating process produces wastewater containing copper, zinc, nickel, chromium and other heavy metals, metal cleaning using concentrated sulfuric acid, concentrated hydrochloric acid and cyanide, not only the dramatic increase in production costs, more contrary to the original intention of environmental protection. The black gold steel nano-penetration layer technology, from the source to eliminate the generation of pollution sources. Whether it is the operation of the production and the later finished product absolutely does not contain any heavy metal substances, the true meaning of green environmental protection.
6 black gold steel nano-coating technology technology applicable to a wide range of materials
The process is applicable to all ferrous materials, from pure iron, mild steel, structural steel, tool steel to a variety of high-alloy steel, cast iron and iron-based powder metallurgy parts.
The technology will not only rapidly take market share from traditional surface treatments, but will also impact the materials market due to its superior performance. Ordinary carbon steel in the black gold steel nano-penetration treatment, the corresponding performance indicators embodied can exceed the stainless steel, in today's market competition is so fierce today, is undoubtedly the manufacturing industry's nuclear explosion.
Currently, a new round of global scientific and technological revolution and industrial change is emerging, China's manufacturing industry is facing the development of the developed countries to build up the advantage and emerging economies to catch up than the double squeeze and challenges, and the metal manufacturing surface treatment industry, networking, intelligent, flexible, service-oriented process, the development of China's manufacturing industry, the mode of development and transformation and upgrading of the impact of a profound.
