Effect of Lost-Foam Casting Process on Properties of Spiral Blade

The wear failure mode of a paver spiral blade was simulated by EDEM software. High-manganese steel, medium chromium alloy and high steel were selected as matrix materials; SiC particles WC surface particle reinforcement the prepared EPC process. performance mechanism analyzed microstructure, hardness, impact, pin disk, erosion test, morphology. Modeling with software applying discrete element analysis method system could simulate actual working situation well. Through simulation, it found that amount from shaft to outside increasing. particle-reinforced wear-resistant coatings on surfaces high-manganese method. coating 5.05 mm, 5.98 7.02 mm. higher content, better diffusion particles. In process soft phase in first worn away concaved, hard protruded bear wear. After wear, sample had best resistance.
