Abstract: The aim of this paper was to determine the influence of the mechanical and thermal
parameters of the matrix materials on their retentive properties. The term ‘matrix retention’ denotes
the capacity of a metallic matrix material to retain diamond particles at the surface of a diamond
tool during working. The bonding is obtained during cooling after the hot pressing process. Proper
mechanical bonding depends on elastic and plastic properties of the matrix. The model
of a diamond particle embedded in a metallic matrix was created using Abaqus software. The
analysis has indicated the mechanical parameters that are responsible for the retention of diamond
particles in a matrix.
