Abstract:
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.
