History of the PMRI PP

• In 1972 Powder Metallurgy Research Institute with
  Pilot Plant was founded
• In 1980 there was set up a Byelorussian Powder
  Metallurgy Research and Production Concern with
  PMRI PP as a scientific centre
• The PMRI PP consists of 4 research divisions and
  the Pilot Plant
• 1. Engineering materials (9 Rlab)
• 2. Porous materials (5 Rlab)
• 3. Materials study and testing (6 Rlab)
• 4. Protective coatings (6 Rlab).
• Pilot Plant

Current Activities of the PMRI PP

• The department of engineering materials fulfils a
  range of research and pilot-technique works on
  development and production of a wide range of
  powder materials, composites and products
  thereof, i.e. constructional materials on metal
  and nonmetal base, frictional and antifrictional
  materials, electrotechnical, ceramic, magnet,
  diamond containing materials, etc.
• The department of porous materials fulfils
  research works on originating permeable materials
  controlled structure from metal and ceramic
  powders and binded foams
• New perspective technologies are developed for
• Purification of Liquid from solid inclusions
• Filtration and Homogenization of Polymer Melts
• Separation of Solid Phase from Liquid and Gaseous
  ones
• Pneumatic Transport of Granular Media
• Melt Filtration of Ferrous and Nonferrous Metals.

• The Department of protective coatings deals with
  investigations of processes of developing
  coatings by thermal (plasma, flame and electro
  arc) metal spraying, by physical deposition and
  develops techniques, equipment and materials for
  coating the parts surfaces to provide the
  predetermined physical and mechanical properties.
• The Department of materials study and testing
  fulfils complex investigations
• Optimisation of composition when fabricating
  materials and products
• Optimisation of technological parameters
• Forecasting of operational criteria, determining
  the reasons for changing the properties when
  operating
• Materials identification.
• On the 1st of January 2001 the personnel of the
  PMRI is 318 officers, including 91 research
  officers, 6 doctors of technical sciences, 38
  candidates of technical sciences

High Temperature Solid Oxide Fuel Cells
The most interesting developments in this field
are technology for manufacturing parts for
low-cost solid oxide fuel cell. Our developments
were initiated by successful elaboration of
technology for production of bearing cathode from
lanthanum-strontium manganites(Fig 1).

manganites

• Now we produce dense and porous tubes from this
  class of complex oxides with length up to 30 cm.
  Our collaborators from RIPhCP assembled small
  SOFC device from ceramics we produce (Fig 2).
  This SOFC reached current density up to 0.3
  A/cm2.

Ceramic open-cell Foams
The ceramic open cell foams are known to possess
extremely high porosity and permeability,
controlled pore size, high rigidity, low density,
etc. (Fig.1).
Fig.1. Structure of open-cell ceramic form
The PMRI PP have developed
ceramic foams (Fig.2) with the following
properties Open porosity,
75-90
Operating temperature, oC up to 1550
Pore size, number of pores per a linear inch
10-30 Permeability coefficient, m2
10-7-10-9 Max. linear
dimensions, mm 160
Thickness, mm
10-25

foams
The processes for production of the foams have
been already developed

Functional Ceramic

• 1.Wear resistive ceramic
• 2.Ceramic crucible for melting, storage and
  transportation of metals
• 3.Soft ferrite's (L-, E-, U-, T-, P-, C-cores)
• 4.Targets for magnetron sputtering

Plasma Deposition of Thermal Sprayed Ceramic
Coating

• PMRI PP has carried out large complex of works
  for development of technology for plasma
  deposition of thermal sprayed coatings on a
  combustion chamber (Fig.1) and turbine blades of
  1 and 2 stages (Fig.2). Developed thermal sprayed
  coatings of the composition under-layer
  MeCrAlX, coating layer PSZ enable to increase
  difference in temperatures on the coating surface
  and from the substrate of a blade from 50 to 70
  OC at stationary working regime and 100 to 180
  OC at peak regime.

Ceramic Composite Materials for Micro-Electrodes

aluminum oxide powder with glass coating

ultra-sound welding devices

• To save resources and to realize the
  potential capabilities of the ceramic material
  based on alumina we have worked out the
  compositions of the initial charge, which include
  mineralizing addition (Fig.1). Produced
  compound-shape parts (Fig.2) have homogeneous
  structure and uniformly distributed addition in
  the conditions of full-scale production.
