DIFFUSION SATURATION IN
VACUUM
We developed the technologies for depositing of vacuum activated diffusion coatings on the following functional directions:
protection of turbine blades and not cooled chambers of combustion
from refractory metals for engines of small draft of space-rocket
technics. The industrially mastered development provides resistance
of articles in products of combustion of fuel at temperature up to
1600oC. The new development allows to lift maximal
temperature of operation of combustion chambers up to
2000oC.
protection of products from carbon - carbon materials.
The developed coatings provide corrosion resistance on the air in static
conditions 1700oC. The coating heat resisting up to
2000oC - in a stage of development. creation
of heaters for high-temperature atmospheric furnaces (with
temperature of operation up to 1900...2000oC), which
basis is the Mo-W alloys with sheetings. The high resistance to the
thermal swings in "on - off" operating; (more than 50
thermal swings) is the feature of such heaters. The technology is
industrially mastered.
hardening of the cutting and processing tools from a
hard alloy such as WC-Co used for cutting of hard-processed
viscous steels and alloys. protection of crucible, pipes and various kind of equipment
from interaction with liquid metals (including, precious and
aluminium). The development has passed approbation.
hardening of products from a hard alloy such as WC-Co,
including constructional elements of various device used for
manufacturing of artificial diamonds. The development is
successfully mastered in industry. wearresistance and anticorrosive coatings for various
pairs friction, including for bearings of sliding and shaft made
from cheap low-carbon steels; for pumpimpeller used at
downloading of petroleum and gas. The development has passed trial
tests.
anticorrosive coatings for protection of high-coercitive
magnets such as Nd-Fe-B.
