The proposed wear mechanisms of the materials without oil lubrication were the followings : the wear mechanisms of the ferroalloy are adhesive wear , abrasive wear , and some oxidation wear . the wear mechanisms of the composites are abrasive wear and the brittle peeling off . the abrasive wear and the brittle peeling off incr eased with the increase of sic particles content in the composites 在無潤滑條件下,通過對磨痕形貌的觀察,認為鐵基合金的磨損機理主要是粘著磨損和磨粒磨損,同時伴隨有一定程度的氧化磨損;加入sic后主要是磨粒磨損和脆性剝落,且sic越多材料的脆性剝落越嚴重。

Xinyu city is famous for steel production , so with the name of he city of steel listed the 55th among the national 500 biggest industrial enterprises , whose steel output accounts for 80 percent of the whole province , and whose ferromanganese alloy s output ranks the first in china , the xinyu steel and iron co . ltd is the largest steel and iron base of jiangxi province and the base of ferroalloy of the county 新余憑鋼建市,素有“鋼城“之稱。新余鋼鐵有限責任公司是江西最大的鋼鐵生產基地,全國重點鐵合金生產基地,為普特鋼兼有的大型冶金聯合企業,曾名列全國500家最大工業企業第55位,鋼產量約占江西80 % ,錳鐵合金居全國首位。

When sintered at 1050c , the wear resistance of the composites were better than that of the ferroalloy under both low and heavy load without oil lubrication . the wear resistance , hardness , and other mechanical properties of the composites with nickel coated sic were better than those of the composites with bare sic particles . however , when sintered at 1100c , interfacial reaction became so acute that the properties of the composites with nickel coated sic particles was worse than those of the composites with bare sic particles 試驗結果表明:與鐵合金相比,在1050時燒結時,加入適量的sic后,耐磨性有較大的提高;而且加入鍍鎳sic的復合材料的耐磨性、硬度和拉伸強度等力學性能比加入相同含量的未鍍sic的材料的性能要好;在1100燒結時,由于界面反應的加劇,含有鍍鎳sic材料的性能反而比含有未鍍sic材料的性能差。

Because of its excellent properties , such as high strength , high module , wear resisting , and etc . , sicp was added to ferroalloy as a reinforce phase . but the intrinsic difference between the bonds led to poor fabrication of the composites . in this paper , the effects of alloying , sintering , and heat - treatment on the properties and microstructures of sicp / ferroalloy - based composites were studied , : it was found that sic particles reacted with ferroalloy when sintered in 1100 碳化硅因其高強度、高模量、耐熱、耐磨等優良性能而被作為顆粒增強體來制備鐵基復合材料,但因其共價鍵與鐵基體的金屬鍵之間的本質區別導致兩者復合困難,本文擬從基體合金化、燒結及熱處理工藝等方面對鐵合金基復合材料組織與性能的影響進行考察,具體內容如下:加入fe - cu - c基體中的sicp顆粒, 1100燒結時就已經開始發生分解,但反應不強烈,在顆粒表面鍍鎳可以延緩基顆粒與基體之間的反應。
