초록 ▼

A method and apparatus for improving the corrosion resistance of chrome plated materials. After the materials to be chrome plated are mechanically abrasively polished, but before they are reverse etched, they are power washed with a high-pressure liquid. A sprayer with nozzles directed inwardly towards the materials directs water onto the material at pressures in the range of 1000 or 2500 to 3000 psi. After the materials are chrome plated, they are heated above the melting point of a buffing compound, and then the heated materials with the buffing compound applied are buffed. An induction heater is used, before or after the buffing compound is applied. Computer controls, responsive to operator input of the cross-sectional size, composition and/or speed of movement of the chrome plated materials, to in turn regulate the power to an induction coil heater.

대표청구항 ▼

1. An apparatus for improving the corrosion resistance of chrome plated materials comprising: a line for receiving and processing materials to be chrome plated;the line having at a position therealong, an entrance at one, entrance end, and an exit at another, exit end, opposed to the one entrance end;a mechanism for moving the received materials to be chrome plated along the line from the one entrance end to the other exit end during processing;at least one mechanical device intermediate the one entrance end and the other exit end for abrasively polishing the materials to be chrome plated to a finish which leaves integral strands, filaments or “fine hairs” of microscopic size attached;at least one station intermediate the at least one mechanical device and the other exit end for plating the materials to be chrome plated;at least one high-pressure liquid sprayer for removing the attached microscopic size integral strands, filaments or “fine hairs” of the materials to be chrome plated intermediate the at least one mechanical device and the at least one station for plating the materials to be chrome plated;an applicator, intermediate the at least one station for plating the materials to be chrome plated and the other exit end, for applying a non-thermosetting buffing compound to the chrome plated materials by spraying it onto the chrome plated materials, without prior heat treatment of the chrome plated materials;a heater for heating the chrome plated materials after applying the buffing compound; andat least one buffer for buffing the heated chrome plated materials after the buffing compound has been both applied and heated. 2. The apparatus according to claim 1 in which the at least one station for plating the materials to be chrome plated is a reverse etching station. 3. The apparatus according to claim 2 including at least one caustic solution station for treating the materials to be chrome plated, positioned intermediate the at least one high-pressure liquid washer and the reverse etching station as the materials to be chrome plated move from the one entrance end to the other exit end. 4. The apparatus according to claim 1 in which the liquid is water. 5. The apparatus according to claim 1 in which the pressure is greater than 100 psi. 6. The apparatus according to claim 1 in which the pressure is in the range of 1000 to 3000 psi. 7. The apparatus according to claim 1 in which the pressure is in the range of 2500 to 3000 psi. 8. The apparatus according to claim 1 in which the at least one high-pressure liquid sprayer has a pair of opposed nozzles that are directed towards each other. 9. The apparatus according to claim 1 in which at least one high-pressure liquid sprayer has a plurality of nozzles that are inwardly directed towards the materials to be chrome plated.
