Definitions

  • An abrasive mixture for abrading material from the surface of a workpiece is provided with improved cutting characteristics and lower temperature operating capability along with ease of cleaning through the inclusion of solid lubricant particles in the mixture including an inert powder matrix, abrasive particles and sufficient low vapor pressure water miscible liquid binder to provide a paste of a consistency desired for the intended operation.
  • One mixture described includes mica particles as the solid lubricant in a clay powder matrix including abrasive particles such as silicon carbide along with a liquid glycollic compound binder.
  • the present invention provides an abrasive honing mixture which includes solid lubricant particles rather than a liquid lubricant.
  • the mixture consists essentially of, by volume, a clay powder, preferably 5-25 parts; abrasive particles, preferably 25-45 parts; along with solid lubricant particles, preferably 25-30 parts; and sufficient low vapor pressure water miscible liquid, preferably a glycollic compound, to form a paste.
  • the present invention in its preferred form comprises (a) a colloidal clay powder such as bentonite as a matrix or carrier and preferably in the range of about 5-25 parts by volume, (b) solid lubricant particles such as of mica to improve mixture flow and to reduce internal I friction within the matrix and preferably in the range of 25-30 parts by volume, (c) abrasive particles such as silicon carbide, boron nitride, diamond, aluminum oxide, etc., and preferably in the range of about 25-45 parts by volume, (d) with the balance a low vapor pressure liquid to avoid evaporation and hence hardening of the matrix and miscible with water for ease of cleaning, for example, a glycollic compound such as ethylene glycol. Amounts in the range of 20-30 parts by volume along with the quantities of materials described above has been found to be particularly useful.
  • the above ingredients were thus combined in the range of two parts by volume each of mica, silicon carbide and ethylene glycol with one part by volume of western bentonite.
  • the mixture was prepared by blending to reasonable uniformity.
  • gas turbine engine nozzle segments were mounted in a fixture which was placed in a chamber including the above described mixture. The fixture carrying the segment was then reciprocated within the mixture until desired surface characteristics were produced.
  • a nozzle segment in the cast condition had a surface finish of 50-80 RMS. After reciprocal movement through the above described media for a period of about minutes, a surface finish of 2-10 RMS was attained.
