Definitions

  • a process for coating rubbing surfaces comprises projecting onto the said surfaces, simultaneously, by means of at least two oxy-acetylene flame or plasma flame guns, on one hand, carbon steel and, on the other hand, nickel and aluminium forming, by combination with the oxygen supplied by gun, a composite material comprising nickel aluminides and oxides with substantially ellipsoidal grains, the said composite material, which can also be made to contain, by incorporation on the projection, of spherical grain particles such as silicon carbide and/or titanium boride and/or boron carbide, being alloyed with the carbon steel to form a wear resistant layer, favourable to sliding and averaging a certain minimal thickness, resisting well the high contact pressures developed, according to the method of production preferred, during the operation of the engine,
  • an element with a rubbing surface said element being arranged so that the said surface is covered with a wear resistant layer constituted by an alloy of carbon steel and a composite material formed principally of nickel aluminides NiAl and Ni Al which occur in substantially equal parts with, in smaller proportions, oxides with substantially ellipsoidal grains NiO, A1 0 and NiA1 O which are formed by reaction during the operation and with which may advantageously be incorporated,
  • the invention consists, apart from these principal features, in certain other features which are preferably incorporated at the same time and which will be more explicitly described below.
  • the envelope 1 is then brought to a temperature of about C. so as to produce, as explained below, a final prestressing.
  • a first passage is advantageously effected during which only the aluminium and nickel gun discharges, so as to deposit a thin keying film of composite material formed of aluminides of nickel and of oxides (of thickness generally comprised between 0.02 and 0.05 mm.), over the whole of the surface 2.
  • proportions by volume may vary between 10% and 90% of carbon steel of which the content of carbon is between 0.4% and 1.2% by weight.
  • the proportion to be followed for aluminium and nickel may vary between 90% and 10%, the aluminium and the nickel occurring in substantially equal amounts.
  • a steel with 0.6% approximately of carbon is selected and a proportion, by volume, in the region of 60% of steel for 40% of complementary part in which aluminium and nickel are in substantially equal amounts.
  • the proportions, by volume of the materials to be alloyed are in the neighbourhood.
  • the two guns are made to discharge during as many passes as is necessary to obtain a layer 3 of thickness at least equal to 0.3 mm. This thickness confers on the said layer good resistance to contact pressures exerted by the piston.
  • the projection of the wear resistant layer 3 is effected very rapilly and, on the other hand, the materials used are relatively cheap in comparison with other materials tried and which gave worse results, the method of coating and the envelope obtained by the invention have been found to be very economical.
  • a method of forming a coating on a rotary piston engine element constituted of light alloy comprising projecting on the surface of said light alloy element, simultaneously, by means of at least two flame guns, carbon steel from one said gun, and, nickel and aluminum from another said gun, forming, by combination with oxygen supplied by the gun, a composite material comprising nickel aluminides and oxides with substantially ellipsoidal grains, said composite material alloying with the carbon steel to form said coating.
  • the materials to be alloyed of 35% to 38% constituted by the aluminum and nickel in substantially equal amounts and from 5% to 2% of particles, with spherical grains of diameter from 1 to 3 said particles being composed of at least one of the substances silicon carbide, titanium boride and boron carbide.
  • a method according to claim 6, comprising causing tfihe gun producing said composite material to discharge 8.
