Hard alloy anvil is an important component in the production of artificial diamond press, and it bears alternating loads of high temperature and pressure during the diamond synthesis process. Its lifespan directly determines the production cost of diamond synthesis.
Principle
The domestic synthetic diamond industry mainly uses the hexahedral top synthesis process, which belongs to the static pressure catalyst method. The basic principle is to use six hard alloy anvils on each of the six faces, while acting on the high-pressure cavity composed of hexahedral pyrophyllite, causing the graphite in the cavity to transform into diamond through high-temperature and high-pressure catalysis.
Performance
1. High hardness and compressive performance (HRA>91, pressure resistance above 5000MPa);
2. High strength and toughness (hard alloy anvil needs to withstand significant tensile stress>35kg/mm2 on the inclined surface during operation);
3. High temperature resistance, wear resistance, and corrosion resistance (during the synthesis of diamond, the transition temperature of C element is about 2000 ° C, and the added catalyst should be conducive to the synthesis process and not react with the top hammer)
Introduction to Hammer Grades
The top hammer products we produce currently use brands PLO8D and PL10D. The two brands use high-quality independently developed WC raw materials, combined with precise pressing and forming technology, and adopt the world's advanced PVA sintering furnace for integrated sintering, to maximize the physical properties of the top hammer product, such as compressive strength, bending strength, thermal fatigue resistance, and thermal shock resistance.
The top hammer undergoes ultrasonic testing and magnetic non-destructive testing before leaving the factory, and can provide efficient aging treatment to eliminate internal stress according to customer needs.
Introduction to the Applicable Scope of Hammer Grades
| shop sign | Density(g/cm³) | HRA | TRS/MPa | Scope of application |
| PL08D | 14.65±0.05 | 91.3±0.5 | 23600 | Universal grade, high compressive strength, good comprehensive performance, suitable for synthesizing superhard materials under most working conditions, such as diamond, cubic boron nitride, and other products. |
| PL10D | 14.5±0.05 | 91.7±0.3 | 23600 | Diamond cultivation with specific grades, high thermal stability, and good fracture toughness. |
Product Specification Introduction
Hammer numbering rules
Each top hammer of Penglai Superhard Composite Materials Co., Ltd. has a unique number, making it easy to track it from production to use throughout the entire process.
D: Represents the minimum arc diameter of the outer diameter of the hammer, in mm
E: Width of small top surface, unit: mm
F: Refers to the width of the small slope, in millimeters
H: Refers to the total height of the product
