The Joint Institute of Mechanical Engineering offers customers the technology of diamond-containing metal-matrix composite for magnetic-abrasive machining under a commercial agreement with technical assistance and/or a licensing agreement and is looking for partners to conclude a technical cooperation agreement.

Diamond-containing metal matrix composite (MMC) technology for magnetic abrasive machining (MAM) is a cutting-edge research and development technology. It is based on the creation of composite ferroabrasive powders (CFAPs), where the matrix consists of a ferromagnetic metal (usually iron) embedded with micro- or nanoparticles of diamond (synthetic or natural impact diamond). When exposed to a magnetic field, these granules align into an "elastic brush," providing ultra-precise final polishing of parts.

Since this technology lies at the intersection of materials science and precision engineering, the main patent holders, developers, and manufacturers are research institutes, academic centers, and specialized companies.

The primary developers and users of the technology are:
1. JSC Research and Production Complex "Abrasives and Grinding" (RPC "AS") / ISSP RAS (Russia).
Russian academic research and specialized enterprises are actively developing methods for synthesizing metal-matrix composites, including using magnetic pulse pressing and thermobaric processing. These technologies are supervised by RAS institutes (in particular, the Institute of Solid State Physics) in cooperation with production facilities.
Status: Development of compositions, patenting of CMAP sintering and grinding technologies, industrial production of diamond grinding powders.
2. Hyperion Materials Technologies (USA / Global Market)
A global giant in the development of superhard materials and metal-matrix solutions. The company possesses advanced technologies for the incorporation of diamond micropowders into metal and polymer matrices for precision finishing. The largest commercial manufacturer of complex diamond abrasives, supplying components for adaptive polishing systems, including magnetic media.
3. Institutes of the Chinese Academy of Sciences (CAS) and specialized companies (including E-Grind).
China leads in commercial production of polycrystalline diamond powders and composites produced by directed explosion and sintering. Key materials science laboratories, supported by commercial brands, are developing MAO and CMAP technologies.
Status: Mass production and patents for MMC optimization (including aluminum-matrix and ferro-matrix compounds).

Belarus occupies a leading position globally in the development of composite powders for MAO. Scientists from academic institutes have created the first unique "iron-impact diamond" MMCs based on tagamite, which are superior in durability to synthetic diamond composites.

The Joint Institute of Mechanical Engineering has developed a diamond-containing metal-matrix composite (AMMC) for tooling.
"Iron-nanostructured impact diamond" is used in magnetic abrasive surface treatment technologies for various hard-to-machine materials (metals and alloys, ceramics, glass, semiconductors, and superhard materials) used in mechanical engineering, optics, microelectronics, nuclear engineering, and toolmaking.

The information is published in the Catalog "100 Best Developments of the National Academy of Sciences of Belarus for the National Economy in 2022–2023," 2024, pp. 90–91. (in Russian)

Technical advantages (compared to the best domestic and foreign analogues):

AMMK with a particle size of dk = 10–150 µm provides 1.5–1.7 times higher polishing productivity than the best foreign analogues and, depending on the impact diamond particle size (dа = 0.3–5.0 µm), can be used for polishing and fine grinding critical parts with high precision and roughness requirements (Ra = 0.1–0.02 µm). Compared to analogues, it offers 1.5–2 times greater durability of the powder working medium.

Pilot industrial testing of AMMK was carried out.

The Joint Institute of Mechanical Engineering completed the R&D project "Develop a technology for producing magnetic-abrasive process media based on nanostructured wear-resistant composites, including those containing impact diamonds, using mechanosynthesis; create process equipment for magnetic-abrasive processing of optical, microelectronic, and nuclear energy products; and organize production of the developed products."

The results were used in the development of the technology.
