Antifriction properties of cermet piston rings

Conclusions

  1. 1.

    The results of tests carried out on the MT-62M machine under laboratory conditions are in good agreement with the data obtained in testing the same materials in automobile and tractor engines; this implies that the design of the machine and the experimental procedure used can be used for qualitative (and often quantitative) evaluation of the antifriction properties of materials.

  2. 2.

    By alloying the iron base of materials with carbon, copper, and phosphorus, producing singlephase pearlitic structure, it is possible to reach and exceed the wear-resistance of the gray cast iron only.

  3. 3.

    The wear-resistance of chromium-plated cast iron can be reached by alloying the iron - graphite base with chromium. However, owing to the deterioration of other antifriction characteristics, these materials are not the best for use in the manufacture of piston rings.

  4. 4.

    The investigated lines of development of a cermet piston ring material (alloying of the iron base with carbon, copper, phosphorus, and chromium) fails to provide an adequate basis for recommending this material for the intended purpose and stresses the need for developing a material based on different principles [18].
