Abstract: Objectives: As a typical difficult-to-machine material, polycrystalline CVD diamond often requires sophisticated and time-consuming polishing methods to achieve a smooth surface. In this study, a non-contact polishing method based on atmospheric inductively coupled plasma is investigated for the pol...
Abstract: Significance: As the hardest material, diamond is widely used in various cutting and grinding tools. During the preparation process of diamond tools, thermal damage to diamonds is almost inevitable. The thermal damage to diamonds primarily includes graphitization, breakage, cracking, and chemical e...
Abstract: Objectives: The aim was to prepare a variety of non-stoichiometric (Ti, Nb)Cx PCD tool binder composites using TiC and transition metal Nb by mechanical alloying (MA) technology. The effects of different sintering temperatures and Nb contents on the phase compositions, microstructures, and mechanic...
Abstract: Objectives: Diamond tools are widely used in fields such as oil drilling, geological exploration, and stone processing, among which sintered metal bond diamond tools have become the most representative due to their wide applicability and strong durability. Cobalt (Co) has become the preferred materi...
Abstract: Objectives: With the improvement of production technology, the traditional diamond particle cleanliness detection method can no longer meet the requirements of high precision, high quality and high automation in the diamond industry due to its low efficiency and poor accuracy. The rapid development ...
Abstract: Objectives: With the depletion of easily recoverable oil reservoirs, the focus of oil and gas exploration and development in China has shifted to "two deeps and non-conventional" oil and gas fields. This transformation is not only accompanied by a significant increase in well depth and more complex...
Abstract: Objectives: SiCp/Al composite is a kind of particle-reinforced metal matrix composite, which offers high specific strength and low density. It is widely used in electronic packaging, aerospace and automobile manufacturing. Although the presence of a large number of SiC particles improves the mechani...
Abstract: Objectives: As the core component of major equipment, the tooth surface accuracy of gears is ultimately guaranteed by the gear grinding process. The electroplated worm grinding roller is an indispensable precision machining tool for dressing worm grinding wheels, which indirectly plays a decisive ro...
Abstract: Objectives: Circular edge chamfering PCD turning tools often feature a chamfered surface at the cutting edge to enhance tool durability. However, the arc at the tool tip causes a large amount of chip accumulation in front of the tool, making chip discharge difficult. This leads to increased cutting...
Abstract: Objectives: Compared with traditional abrasive random arrangement grinding wheels, structured grinding wheels offer better chip space and grinding efficiency during the grinding process. At present, the manufacturing methods for structured grinding wheels mainly include metal sintering, electroplat...
Abstract: Objectives: With the rapid development of electric vehicles (EVs), the maximum rotational speed of EV motors has reached up to 20 000 r/min. Precision polishing of gear surfaces after grinding has become a promising method for improving the noise, vibration, and harshness (NVH) performance of EVs. A...
Abstract: Objectives: During low-temperature micro-abrasive air jet machining, the mechanical properties of materials undergo changes, making the material more prone to brittleness and erosion removal. Comparative experiments were conducted on the low-temperature micro-abrasive air jet machining of hard and b...
Abstract: Objectives: Single crystal silicon carbide (SiC) is known for its high hardness and high chemical inertness, making it chanllenging to process effectively using traditional chemical mechanical polishing (CMP) methods. CMP often struggles to balance processing efficiency and surface quality for SiC. ...
Abstract: Objectives : Titanium alloys are increasingly widely used in the aerospace field, and their research and development significantly influence the advancement of military aircraft, civil aviation, engines, and other high-tech equipment. However, titanium alloy are challenging to machine due to theri s...
