Abstract

The invention belongs to the technical field of ultrahard material machining, and in particular, relates to a diamond composite magnetic abrasive, a preparation method thereof and chemical plating liquid for the diamond composite magnetic abrasive. The diamond composite magnetic abrasive is prepared by the method comprising the following steps: (1) ferromagnetic phase basal bodies and diamond abrasive particles are put in iron plating liquid for chemical composite plating to obtain precursor materials; the iron plating liquid comprises iron salt and phosphorus sources; the substance quantity ratio of iron in the iron salt to phosphorus in the phosphorus sources is (0.2-0.5): (4-7); and (2) the precursor materials prepared in the step (1) are heated to obtain the diamond composite magneticabrasive. The diamond composite magnetic abrasive uses iron-phosphorus alloy plating layers as bonding agents, so that the utilization rate of metal salt in the iron plating liquid is increased, the bonding force between the diamond abrasive particles and the ferromagnetic phase basal bodies is improved, and meanwhile, the pollution caused by nickel is prevented.

Description

technical field [0001] The invention belongs to the field of superhard material processing, and in particular relates to a diamond composite magnetic abrasive, a preparation method thereof, and an electroless plating solution for the diamond composite magnetic abrasive. Background technique [0002] Diamond magnetic abrasive is a composite abrasive with magnetic properties and abrasive grinding ability. Compared with traditional diamond abrasives, this composite abrasive can not only be used in traditional diamond grinding and polishing applications, but also can be combined with modern finishing technology to achieve grinding and polishing of special shapes such as spherical surfaces, three-dimensional curved surfaces, inner and outer circular surfaces, etc. Wide application prospects. [0003] The methods of preparing magnetic abrasive mainly include bonding method, casting method, chemical method and sintering method. Among them, the bonding method and sintering method ...
