Application: development using induction surfacing of protective coatings on flat and curved surfaces of quick-wear parts of construction, agricultural and other machinery.
Advantages: reducing the cost of protective coating due to the use of waste of machine-building enterprises (fraction, chips, etc.) at 20–80 %. The process of applying a protective coating can be carried out in individual, small-scale and large-scale production. Flexible control of the structure and properties of the protective coating according to customer’s requirement. The possibility of additional heat treatment after hardening. Wear resistance of protective coatings under conditions of abrasive wear is 30–90 % higher than that of analogs.
Key features: the intensification of the process of diffusion alloying compared with fixed in 3–7 times. Coating structure is composite with a reinforcing phases in the eutectic matrix. Hardness of cladded protective layer 55–68 HRC. Thickness of protective coating up to 5 mm.
Developed: Research Laboratory of Steel Products Hardening, Dr. Vladimir Dashkevich, PhD (Cand. of Techn. Sci.).
