But when the test load is increased, the wear mechanism is dominated by spalling, and the test material weight loss is raised, therefore, the amount of hard phases can be decreased advisably. high carbon high alloy steel, hard phase, friction and wear

The wear surface morphologies showed that the mechanism of the 45 steel was micro-cutting and plastic deformations, and the mechanism of high chromium cast iron was micro-cutting of matrix structure and desquamating of carbide particles under the sand slurry wear condition.

对于象45钢这类较软的材料，在泥沙磨损条件下，材料的磨损机理主要是显微切削和多次塑性变形。对于含有较多高硬度碳化物质点的高铬铸铁类材料，在泥沙磨损条件下，材料的磨损机理主要是基体组织的显微切削和碳化物颗粒的脱落。

Among them ability of richening nitrogen about 96% can be achieved using 1~# carbide of brown coal in condition of bed bigh 1.5m, bed diameter 0.02m, rich nitrogen ...

其中1~＃褐煤碳化物在床层高度 1.5m，直径 0.012m，富氮气体流速 123Nml／min，操作压力 4×10~5 Pa的条件下，富氮能力可达 96％左右，并通过分子试探等温线的分析，探讨了碳化物的孔隙特性。

This is believed to be conneeted with the depletion of Mo, a scavenger of P, in matrix due to the Mo tithed carbides formation during preaging. Therefore, more P is released and segregated to grain boundaries. Carbide coarsening perhaps contributed to the increment in transition temperature too.

Mo可抑制磷的偏析，但因时效过程中富Mo碳化物的生成和长大，使基体中Mo的含量降低，因此，磷从Mo的&束缚&下&解放&出来并偏析到晶界，使脆性转变温度升高，此外，碳化物的粗化也可能导致脆性转变温度升高。

In as-cast microstructures, SG modification can refine austenites and inhibit their orientational arrangement, reduce and refine the intercrystalline carbides; in heat-treatment process, SG modification can either shorten the holding time or lower the holding temperature.

SG 变质处理能有效地抑制铸态组织中柱状晶的生长，细化奥氏体组织并降低其方向性，减少晶间碳化物数量并使之细化；对热处理组织，SG 变质处理可以加速碳化物溶解，缩短水韧处理的保温时间或降低水韧处理的温度。

The volume fraction of carbides in the alloys was measured.

分析了碳化物对铸态组织的影响以及合金成分与碳化物类型、体积分数之间的关系。

The process of Covering Cr12MoV steel with Carbides in fused salt was studied.

本文研究了Cr12MoV钢在熔盐中的碳化物覆层技术，介绍了覆层工艺方法，探讨了该工艺的机理，测试了碳化物覆层的性能。

The high temperature abrasive wear test was carried out on a high temperature friction and wear test rig whose test atmosphere can be controlled.

结果表明：碳化物的抗氧化稳定性以及碳化物与基体的氧化大无畏同性对合金在大气气氛中的高温耐磨性起着重要的作用。

Meanwhile, it is also illustrates that the smaller chromium carbides have less restriction to formimg thin splats than larger ones, which beneficial to limit the size of pieces removed by impact of the sand particles, and the higher volume fraction of small chromium carbide may effect the erosion through enhancing interlamellar bonding of the splats which leads to increase the erosion resistance of the coating.

揭示了细小碳化物颗粒有利于获得扁平粒子厚度较小的涂层结构，可减小涂层冲蚀磨损过程中每次剥落的体积；较高含量的细小碳化物颗粒有利于提高涂层扁平粒子间的结合，从而提高涂层抗冲蚀磨损性吉臣。

But we don't care about Battlegrounds.

但我们并不在乎沙场中的显露。

Ah! don't mention it, the butcher's shop is a horror.

啊！不用提了。提到肉，真是糟透了。
