Spark Plasma Sintering (SPS) is an advanced pressure sintering technology that uses the instantaneous high temperature, surface activation, and discharge impact pressure generated by pulse discharge to achieve rapid sintering of powders.
Spark plasma sintering is applicable to almost all types of materials such as metals, ceramics, and composite materials. It is of great significance for achieving high-quality, high-efficiency, low-cost and low-consumption material preparation. It can also be used for connection, molding, surface modification, etc.
SPS integrates plasma activation, hot pressing, and resistance heating, and has outstanding advantages such as fast heating speed, short sintering time, controllable organizational structure, energy saving and environmental protection, and has important application potential in the preparation of high-performance materials. The SPS sintering press produced by Seiko Ruiyi has outstanding features such as accurate and flexible temperature measurement method, high-precision pressure control system, high-load frame structure design, efficient and reliable cooling system, complete and convenient operating system, energy-saving and reliable pulse power supply, etc.
1.1 Purpose: Used for sintering blanks composed of powders such as refractory metals (such as tungsten, molybdenum, rhenium);
1.2 Maximum length of workpiece: 900 mm;
1.3 Maximum sintering length: 800 mm;
1.4 The maximum cross-section of the workpiece is 20×20 mm
1.5 Maximum sintering temperature: ≮3000℃;
1.6 Sintering environment: Pressureless sintering is performed under atmospheric pressure conditions. Hydrogen is used as a protective gas during the sintering process to ensure that the blank is in a reducing atmosphere during the sintering process to prevent oxidation;
1.7 Sintering form: resistance heating method, electric current passes through the workpiece itself. During sintering work, the operator performs in a standing position. The viewing window is located at operator eye level. The observation is equipped with blinds to protect the observation window glass from high temperature radiation and metal vapor condensation.
