Paper Title:
Study on Surface Modification of Feed Bulking Machine Extuding Screw
  Abstract

Ionitrriding and plasma arc surface quenching are seprately used to harden screw surface for settling the wearing problem of bulking machine extruding screw during the feed production process in the paper.The results indicate that surface hardness is incresed 1~2times and the depth of harden layer is about 0.15~0.3 millimeter by ionitrding,but plasma arc surface quenching can improve the surface hardness of screw 2~3times, and the depth of harden layer is about 0.2~0.45 millimeter. Metallurgical structure of harden layer is also analysed and discussed.
