The paper also presents the investigation of microhardness surface and fracture zone feature crystalline structure and chemical composition of TiN TiC and Ti ( C_xN_y ) super-hard coatings . Finally the paper gives out application cases of the PCVD technique in the cold extrusion punch .
并对其制备的TiN、TiC、Ti(C xNy)超硬膜进行了显微硬度和化学成份等分析,最后介绍了该项技术在冷挤压 冲头上的应用实例。
In the late game also try putting Zone Troopers or Missile Squads into the supplied APCs and get the Mortar upgrade for added punch .
在游戏人物等级后期,能够试着方一些 重装步兵或者导弹兵到提供的运兵车里,升级迫击炮以增加 威力。
For the defects such as dead zone and shrinkage cavity in conventional extrusion process an inner cone punch was proposed to improve the metal flow behavior .
针对平模挤压过程中易产生死 区、缩孔等流动缺陷,设计一种带内锥 冲头 用以改善成形过程中金属的变形流动行为。
