Theinvestigation of physicometallurgicalphenomena forthe CC formingof WCP/ Fe Ccom posites wasperformed. Resultsshow that underthe patentcondition, WCP/ Fe Ccomposite surfacelayerof16 20 m m heavycross sectioncan beacquiredintheoutsideofa hollow cylin der. The surface of CTC particlescould be partially dissolved by Fe containing melt. Thefineshortstick like WCcrystallitesarein situseparated neartothesurfaceof CTC particles.Far from the CTC particles,someseparated, finetungsten carbidecrystallitesand Fe, W,Mo and Cretc. containing web composite carbides, are distributed on the matrix of WCP/ Fe Ccomposite. Fe Calloy matrix of the hollow composite cylinder is alloyed in differenthigh levels.

腐蚀学报（英文）
漂染车间的防腐施工仝奎(郑州大学建工学院郑州450052)漂染车间内酸、碱蒸汽含量高,造成车间内湿度很大,当温度下降到露点开始结露,在金属和墙壁表面形成大量液膜,这层液膜中含有各种腐蚀成分,造成对漂染机台和厂房的腐蚀.某针织厂厂房设计时,忽视了防腐措施,使用近三年,混凝土上梁的表面已开始粉化脱落,墙面也有腐蚀的痕迹,此车间下层为漂染车间,上层有重达数十吨的烘干及定型设备,若一旦混凝土梁柱遭受腐蚀破坏,后果将不堪?...
