    摘要: Creping doctor blades useful for making soft tissues are substantially improved by ion nitriding the surface(s) of the doctor blade to produce a hardened surface while retaining the resilient interior of the non-treated blade. The resulting blades have approximately a three-fold increase in blade life.
