Gel-casting Preparation of W-Cu Composites with Complex Shape AITranslate
Abstract AITranslate
W-Cu blanks with complex shape were prepared by non-aqueous gel-casting. The effect of disper- sant content and solid content on slurry viscosity was investigated. The blank drying curve was drawn and the drying system was established. Microstructure and bending strength of the blank were characterized. The results show that when the dosage of dispersant is 0.15%（ mass fraction and based on the quality of the metal powder）,slurry viscosity reaches the minimum and the slurry can obtain 45% （volume fraction） solid to meet the requirement of gel-casting. The blank is dried firstly at room temperature for 10 h and then placed in a constant temperature drying oven at 100℃ for 8 h to obtain W-Cu blank without deforma- tion and cracking on its surface. With the increase of solid content, both the density and uniformity of the blank increase. The blank has good surface quality and its bending strength can be up to 26.9 MPa.
