Composition of the material: Powder antifriction material on the base of iron with additives of solid lubricant from fusible metals PA-GZGr2D20S10
Main characteristics of the material:
- ● Porosity – 18 - 25 %;
- ● Oil absorption – 1,8 % minimum;
- ● Destruction effort at radial pressure – 950 … 1 000 MPa minimum;
- ● Friction coefficient (at Р = 2,8 MPa, v = 4 m/s) – 0,015 … 0,03;
- ● Gripping pressure – 4.2…4,5 MPa;
- ● Wear intensity (at Р = 2,8 MPa, v = 4 m/s) – 34,7•10-12 mkm/km
Type and characteristics of products: Inserts of starters for cars and trucks being made from this material are characterized by higher mechanical and tribotechnical properties and by advanced conditions of self-lubrication in comparison with bronze.
An output mastery of developed products: An output of the production is mastered at the Pilot Plant of O.V.Roman Powder Metallurgy Institute. Yield is 2,0 million pieces per year.
Novelty: The patent is in force in CIS countries.
