Raw material
Diamond micron powders are high toughness, thermally stable, intact crystals of high quality, with equilateral shape, transparent crystal, standard size, narrow size distribution, PPM cleanness and non-magnetic properties. The carbides we select have a coarse crystalline structure with super hardness, high wear resistance, great bending strength, and heat and corrosion resistance.
Product research and development
Designing and testing products to customers' requirements to meet analysis of verification and validation, failure mode and reliability, and to carry out pre-production and batch production.
Structure inspection
Product size and shape are precisely measured by an Optical Microscope Imaging Apparatus (OMIA). The Scanning Electron Microscope (SEM) is used to probe the micron-scale structure. Defects such as flaws, delamination and holes hidden inside the products are tested by Scanning Acoustic Microscope (SAM).
Thermal stability test
Differential scanning calorimetry, thermogravimetric and differential thermal analysis (DSC-TG-DTA). When heating PDC in an oxidising atmosphere, we measure the initial oxidation temperature, mass loss rate and weight loss ratio to determine the degree of oxidation and heat resistance.
Wear resistance ratio
The wear resistance ratio indicates the abrasion resistance of PDC. It is defined as the ratio of the standard wheel weight loss to the PDC diamond layer weight loss after the PDC is ground by the wheel. Abrasion resistance is in direct proportion to the ratio. The heat wear resistance ratio is the abrasion resistance of PDC after heat treatment and reflects the abrasion variation of PDC.
