Patent CZ-51396-A3 (CZ)
Title: Process of treating at least one part of magnetically soft material
Inventor: LIEDTKE DIETER
IPC: C23F17/00
Filed: 1995-06-16
Abstract: In prior art methods of treating weakly magnetic components by annealing and producing a wear-resistant layer, the annealing is first carried out in one device, followed by cooling and temporary storage, and the wear-resistant layer is then produced in another device. A method of this kind is expensive and time-consuming and involves the risk that, following the annealing, the surface of the components is contaminated. The method proposed by the invention is designed to give an improvement by avoiding such disadvantages. The method proposed calls for the components made of weakly magnetic material either to be annealed and subsequently provided with a wear-resistant layer in the reaction chamber (61) of a treatment device (56) or the annealing and provision of the wear-resistant layer are carried out simultaneously in the reaction chamber. This renders transfer and temporary storage of the components (1, 16, 34, 48) unnecessary and avoids contaminating them, as well as lowering production costs. The method is particularly suitable for the treatment of weakly magnetic components of solenoid fuel-injection valves.
