Nano-structured hybrid coatings

   

Purpose of the project

Development and implementation of an innovative technology for the production and application of nano-structured ones hybrid protective coatings for molds and sand cores up to 50 Mg.

   

Research & Development

The R&D works planned for implementation will concern the development of the technology of protective coatings and the conditions for the production of structurally complex large-size castings, such as:

use of a hybrid coating

for the limitation of formation defective surfaces around external coolers and elimination internal coolers.

production of long, slender channels

reducing the tendency to cracking and sintering of the mass in them, which makes it difficult to remove it from the channels and the formation of veins in them.

developing a new manufacturing technology of gating channels system

the use of hybrid coatings significantly reduces the number of ceramic fittings used as elements of gating systems.

fabrication of long holes and pockets in massive casts.

effects:

reducing the roughness of castings by at least 50%

reducing the wear of ceramic segments for main spouts by 83%

Increasing the tensile strength of the layer with hybrid coating by min. 20%

63% improvement of the surface quality on which the cooler was installed.

reducing the wear of ceramic segments for main spouts by 83%

reduction of surface defects: veins, scabs of burns on the surface of castings, cavities and holes by 50%

reducing the amount of impregnation and limiting burning and cutting out baked cores by a minimum of 8.5%

reduction of the wear of the protective coating in the full cycle of their production = reduction of the cost of finishing the molds

extension of the service life of tubular ingot molds by 15%

reducing the amount of impregnation and limiting burning and cutting out baked cores by a minimum of 8.5%

increasing the bending strength of sand mold elements by 20%

reducing the permeability of the top layer of the mold with the coating by at least 50%

extension of the service life of the sub-basin slabs by 17%
