“…Metal matrix composites reinforced by nanoparticles have promising properties, which is more suitable for a large number of functional and structural applications than other metal matrix strengthening methods, such as solution strengthening, work hardening and precipitation strengthening [14]. Recently, some researchers investigated metal matrix reinforced with nano-particles (nanotubes), finding out that adding nanosized reinforcement improved hardness, bending strength and wear resistance of matrix [21][22][23][24][25][26][27][28]. Ceramic (Al 2 O 3 , ZrO 2 , TiC, TiB 2 , WC, etc.)…”

Metal matrix-impregnated diamond composites are widely used for fabricating diamond tools. In order to meet the actual engineering challenges, researchers have made many efforts to seek effective methods to enhance the performance of conventional metal matrices. In this work, tungsten carbide (WC) nanoparticles were introduced into WC-Bronze-Ni-Mn matrix with and without diamond grits for improving the performance of conventional impregnated diamond composites. The influence of WC nanoparticles on the microstructure, densification, hardness, bending strength and wear resistance of matrix and diamond composites were investigated. The results showed that the bending strength of matrix increased up to approximately 20% upon nano-WC addition, while densification and hardness fluctuate slightly. The grinding ratio of diamond composites increased significantly by about 100% due to nano-WC addition. The strengthening mechanism was proposed according to experimental results. The diamond composites with 2.8 wt% nano-WC addition exhibited the best overall properties, thus having potential to apply to further diamond tools.

“…Recently, the use of nanoparticles, including carbon nanotubes (CNT), in crushing and polishing tools, as coating materials too, has become very attractive [74][75][76][77][78][79] and the reported data [74] demonstrate that the addition of CNT tends to lower the grain size of the structural constituent of the binder determining higher strength and performance to the metallic binder.…”

Among other materials, hard metals represent an important family of functional materials. They show properties that are combinations of those of their constituents. The general idea while using hard metals is to exploit their excellent properties in terms of hardness, toughness, wear resistance, and chemical stability. These characteristics made hard metals as promising candidate for use as a cutting tool, which constitutes their main area of application. Depending on the particular use, the most important properties can be achieved: (i) by properly selecting the constituents made up the whole composition, (ii) by varying the relative composition of the phases, or (iii) by applying a suitable hard metal coating layer on the top of the cutting tool. This chapter presents a general overview of the actual scenario concerning different tool materials, including a short history and description of state-of-the-art techniques as regards their composition, their manufacturing routes and their most important properties. Some results of the own research in this field are carried out during the years will integrate this part.

“…c o m / l o c a t e / m a t d e s metal binder is solved by an additional coating step, which complicates the manufacturing process and increases costs. Another efficient method to enhance the mechanical properties of various binders is to add a controlled amount of nano additives (e.g., WC, ZrO 2 , Al 2 O 3 , and carbon nanotubes), which allows improving performance of diamond tools considerably [23][24][25][26][27][28][29]. A significant increase in performance of tools with tungsten carbide alloyed binder was reported [27,28].…”
