摘要

"IMPROVEMENTS IN THE CEMENTING OF FILTERS OF CUTTING INSTRUMENTS", characterized by the fact that, prior to a mechanical and electrolytic washing and degreasing operation, of the cutting instrument and cutting edge or edges to be treated, a preheating of the substrate is carried out. steel to be coated, placing cutting instruments in an oven, in which they remain the time required to reach the appropriate temperature to provoke in the subsequent phase, the rapid evaporation of the liquid vehicle in which a homogeneous dispersion of polytetrafluoroethylene has previously been reproduced, to which a small percentage of rhodium oxide can be added, so that, when projecting and driving in pulverized form, directly against the cutting edge or cutting edges and adjacent bevels that determine it, the said homogeneous dispersion, the sudden evaporation occurs of the liquid carrier vehicle, which has served for the regular and uniform distribution of polytetrafluoroethylene, with or without addition of rhodium, the temperature of the preheated substrate contributing to fix, by adherence to contact, the small projected particles, which form a regular and uniform deposition or layer on the treated area.
