NN IMZ-13-01. Highly effective technologies for manufacturing bimetals using laser and combined processes – INNOVATIONS OFFICE

The economic expediency of using the proposed methods of production of bimetallic materials is:
- in significant and rational saving of material and energy resources;
- reduction of the specific cost of used production areas and labor costs;
- the possibilities of optimizing the choice of the most effective method of manufacturing bimetals.
It is shown that the time spent on the implementation of the mentioned technologies, depending on the complexity, is from 3 to 12 months.

Laser - casting and combined methods of manufacturing bimetals of various sizes and geometric shapes have been developed and implemented , which make it possible to reduce the cost, increase the productivity and quality of manufacturing bimetals without losing functionality and work resource
The developed technologies make it possible to manufacture bimetals with a guaranteed metallurgical connection between the functional layer and the base

Temporary resistance to destruction (depending on the thickness of the bimetal)	450...500 MN/m2
Grafting strength per section	150...200 MN/m2
The cost of 1 m2 of bimetal with a thickness of 1 to 10 mm	from UAH 5.6 thousand. up to UAH 62,000
Economic efficiency of using bimetal to solid	from 3.2 to 22 thousand UAH/m2
Dimensions	0.5x1m to 5x10m

The cost and productivity of bimetal production depend on the characteristics of the functional layer:
- chemical and phase composition;
- its thickness and hardness;
- adhesion strength to the base;
- geometric dimensions
