Abstract
Methods and equipment for controlling the temperature of particles in polishing processes by means of solid particles and/or solid particles containing an electrolyte, in a liquid environment. The method includes a step of aspirating the liquid from the container where the particles are located; a step of thermally adjusting the liquid; and a step of reincorporating the liquid after its thermal adjustment into the container to control the temperature of the particles. And the equipment includes: a duct circuit, with an inlet mouth and an outlet mouth in the container; a suction pump; a filter with a mesh that does not allow particles to pass through; and a heat exchanger.
Claims20
A method for surface treating a metal part through ion transport using electrically conductive solid particles, the method comprising:
- electrically coupling the electrically conductive solid particles to a first pole of a current generator, the solid particles being at least partially immersed within a liquid inside a container;
- electrically coupling the surface of the metal part to a second pole of the current generator;
- contacting the surface of the metal part with the solid particles;
- during the surface treating of the surface of the metal part, aspirating to outside the container at least part of the liquid in which the solid particles are immersed;
- altering the temperature of the aspirated liquid;
- and
- reintroducing the temperature altered liquid into the container to regulate the temperature of the solid particles.
Equipment for controlling the temperature of particles used in surface treating a metal part through ion transport, the particles comprising solid particles and/or solid particles loaded with an electrolyte liquid and immersed in a liquid, the equipment comprising:
- a container configured to hold the particles and the liquid;
- a duct circuit configured to circulate at least a portion of the liquid, the duct circuit having a first inlet opening and a first outlet opening located at the container;
- a suction pump located in the duct circuit and configured to produce a suction at the first inlet opening of the duct circuit to aspirate the liquid, the suction pump being configured to circulate the liquid through the duct circuit;
- a filter located in the duct circuit upstream the suction pump, the filter having a mesh of a size that permits passage of the liquid and prevents passage of the particles;
- and
- a heat exchanger disposed in the duct circuit downstream of the filter and the suction pump, the heat exchanger being configured to alter the temperature of the liquid before the liquid is returned to the container through the first outlet opening.
