“…The progressing process of oxidation of the powders could also contribute to the reduction of the sinter density. The material is characterized by a high coefficient of thermal expansion, which ensures good retention of diamond particles in the metallic-diamond composite [1,[8][9][10][27][28][29][30]. The influence of the mechanical parameters and thermal expansion of the matrix on the retention of diamond particles is currently intensively studied, both experimentally and through computer and mathematical modeling [11][12][13][31][32][33].…”

The main purpose of the work was to determine the powder composition and properties of iron-based sinters used as a matrix in metallic diamond tools. The FeCuSnNi sinters obtained from a mixture of commercial powders were used for research. The material was subjected to milling in a ball mill and sinter have been performed with the hot-pressing technique in a graphite mold. The physical and mechanical properties of the sinters were tested. The investigations of obtained sinters concerned density, porosity, hardness, oxygen content, static tensile test and analysis of microstructure. The static tensile test was carried out with the use of a universal testing machine UTS-100. The study of the microstructure of sinters was performed using the JSM-7100F scanning electron microscope. The sinters are characterized by a high coefficient of thermal expansion and good mechanical properties. The FeCuSnNi sinter revealed a complex phase structure. Spot chemical analysis revealed the presence of Fe solution, Cu solution and the presence of iron oxides oxides. Nickel atoms were present throughout the sinter volume. The obtained results indicate that the presented material can be used as a matrix of a diamond-metal composite in diamond tools for the processing of natural stones and building materials.

“…This study shows that the combined effect of high copper content and SiC, alloy composition Fe + 20 wt%Cu + 1 wt%SiC sintered at 1 150°C offer abrasion wear resistance 2 times higher than the other compositions. 29) Yu-Zan Hsieh et al, revealed, effect of coating of diamond grit with active element such as Titanium in iron-based matrix. This form a transitional layer between diamond grit and iron matrix and prevent the degradation of diamond.…”

“…Diamond tools are widely used for cutting, grinding, sawing, drilling, and polishing hard materials, such as stone, concrete, cemented carbides, optical glass, advanced ceramics, and other difficult-to-process materials [1][2][3]. This is due to diamond's unique physicochemical characteristics, namely its extreme hardness and high strength, as well as its good abrasion resistance and low thermal expansion [4].…”

This article presents a review of the current research into the diamond retention capacity of metal matrices, which largely determines the service life and working performance of diamond tools. The constitution of diamond retention capacity, including physical adsorption force, mechanical inlaying force, and chemical bonding force, are described. Improved techniques are summarized as three major types: (1) surface treatment of the diamond: metallization and roughening of the diamond surface; (2) modification of metal matrix: the addition of strong carbide forming elements, rare earth elements and some non-metallic elements, and pre-alloying or refining of matrix powders; (3) change in preparation technology: the adjustment of the sintering process and the application of new technologies. Additionally, the methods used in the evaluation of diamond retention strength are introduced, including three categories: (1) instrument detection methods: scanning electron microscopy, X-ray diffractometry, energy dispersive spectrometry and Raman spectroscopy; (2) mechanical test methods: bending strength analytical method, tension ring test method, and other test methods for chemical bonding strength; (3) mechanical calculation methods: theoretical calculation and numerical computation. Finally, future research directions are discussed.
