Ceramic cutting blades of differing size and thickness varying between0.15-0.60 mm are manufactured by powder injection moulding (PIM) using a feedstock based on the yttria partially stabilised zirconia (TZ-3YS) powder and polyacetal-based system. The injection process ensures a high production efficiency, and is followed by a short catalytic debinding process (1 -3 h) at the temperatures of 105-115C. The sintered blades are machined to the final thickness, and if necessary, undergo an additional heat treatment in reducing conditions to improve the mechanical properties of the product. The influence of the manufacturing procedure on the quality of the final product is discussed. A comparison of the degree of densification, micro-structure and mechanical properties of ceramic knives manufactured by PIM, uniaxial pressing and tape casting is reviewed. 11 refs.
