Description

Ceramic coverings

The ceramic coverings put with methods of a plasma and high-speed gas-flame dusting were widely adopted in the industry thanks to technological effectiveness of production, high hardness, electroinsulating and heat-insulating properties of coverings, permanently high quality of result.

Scope of ceramic coverings is quite wide:

GITsN electrodes with a ceramic covering

  • aircraft, power, gas transport - for a dusting of thermobarrier surfaces on shovels and elements of a hot path of gas-turbine engines;
  • the power - is applied on sealing surfaces of pumps, is also used during creation of electroinsulating bearings;
  • the metallurgy - is used for protection against high temperatures of compression molds, creation of heat-shielding coverings of oven rollers and details of lines of metal rolling;
  • powder metallurgy — protection of products against a carburizing against a graphite substrate;
  • geophysics - for creation of electroinsulating covering of electrodes of GITsN;
  • oil and gas processing - a covering of torch ogolovk;
  • the textile industry - protection of the surfaces which are used up by threads;
  • polygraphy - recovery of geometry of shaft of koronator and aniloksovy ceramic shaft.

Ceramic oxidic coverings, having high hardness, allow to provide additional properties. The main of them are the heat-shielding, thermal stability, electrical insulation, adjustable conductivity, a possibility of a qualitative laser engraving. The ceramic covering is applied both on external, and on internal surfaces of products. At the same time they have to be previously processed.

Shaft with a ceramic covering

Shaft with a ceramic covering

The ceramic covering is made of the following materials:

  • aluminum oxide, electrocorundum. Differs in the high hardness and electrical insulation, it can be operated in the conditions of friction or abrasive wear, and also for protection of explosive knots". Such ceramic covering can be operated at temperatures up to 1100 °C;
  • chrome oxide - wearproof material which is ideally suited for processing of aniloksovy shaft, consolidations of pumps and details of the textile industry. It can be operated at a temperature up to 540 °C;
  • titanium dioxide - has higher viscosity. It can be operated at a temperature up to 540 °C;
  • the zirconium oxide stabilized by yttrium - the industrial standard for a plasma dusting of thermobarrier ceramic coverings. Temperature of operation varies ranging from 900 to 1250 °C.
