  chromium enrichment
Without chromium enrichment of carbides, no chromium depleted zone is produced to enhance IGSCC susceptibility.
      
Similarly, the width of the region affected by the chromium enrichment was enhanced by tensile straining and reduced by compressive straining, whether the samples were elastically or plastically strained.
      
This process resulted in chromium enrichment as shown by use of X-ray electron spectroscopy.
      
This section of the Lower Branch of the Rouge River exhibits significant lead and copper contamination, as well as measurable chromium enrichment when using either concentrations alone or ratios as methods of comparison.

Brown rice was steeped in CrCl 3 for sprouting to study the effectiveness of its chromium enrichment. The result showed that the sprouting condition and chromium content of the sprouted brown rice varied with the chromium concentration in the solution. It is optimum to steep brown rice in 80 mg/kg chromium solution at 35℃ for about 12 h, thus obtaining chromium-enriched brown rice with sprouts 0.5~(1.0 mm) long, and with the contents of total chromium and organic chromium...

Brown rice was steeped in CrCl 3 for sprouting to study the effectiveness of its chromium enrichment. The result showed that the sprouting condition and chromium content of the sprouted brown rice varied with the chromium concentration in the solution. It is optimum to steep brown rice in 80 mg/kg chromium solution at 35℃ for about 12 h, thus obtaining chromium-enriched brown rice with sprouts 0.5~(1.0 mm) long, and with the contents of total chromium and organic chromium 4 and 11 times higher than the ordinary sprouted brown rice respectively.

以不同浓度的三氯化铬水溶液浸泡糙米并培养发芽 ,研究糙米的富铬效果。结果表明 ,铬浓度对糙米的发芽及其铬含量有影响。 80mg/kg的铬溶液浸泡糙米 12h ,35℃恒温培养至芽长 0 .5~ 1.0mm可获得富铬发芽糙米 ,其总铬和有机铬的含量分别约是普通发芽糙米的 4倍和 11倍。

Microhardness of laser-clad NiCr_3C_2 composite coating on 0.2%C martensitic stainless steel increased with the amounts of added carbide increasing in the considered range. The partial dissolution of Cr_3C_2 particles in the melted pool led to carbon and chromium enrichment in the matrix, and hence caused the formation of much Cr_7C_3, M_ 23 (C,B)_6 and more CrB in the solidifying structures. A higher wear resistance than a single Nialloy coating was achieved in the NiCr_3C_2 composite coating under the...

Microhardness of laser-clad NiCr_3C_2 composite coating on 0.2%C martensitic stainless steel increased with the amounts of added carbide increasing in the considered range. The partial dissolution of Cr_3C_2 particles in the melted pool led to carbon and chromium enrichment in the matrix, and hence caused the formation of much Cr_7C_3, M_ 23 (C,B)_6 and more CrB in the solidifying structures. A higher wear resistance than a single Nialloy coating was achieved in the NiCr_3C_2 composite coating under the condition of dry sliding wear, which was closely related to composition changes caused by forming harder chromium-containing carbides or borides in the Ni alloy matrix resulting from dissolution of Cr_3C_2 particles.

2Cr13马氏体不锈钢表面激光熔覆NiCr3C2复合涂层的显微硬度随Cr3C2粒子添加量的增加而增加;激光熔池中Cr3C2粒子的部分溶解使得Cr、C元素向Ni基体中富集,导致激光熔覆层凝固组织中形成了较多的Cr7C3,M23(C,B)6和CrB化合物,比激光熔覆Ni单一涂层具有较高的干滑动摩擦磨损抗力。Cr3C2粒子的部分溶解使凝固组织中产生了较多的碳铬和硼铬硬质化合物所导致的熔覆层成分变化被认为是改善激光熔覆层干滑动磨损抗力的主要因素。

The morphology and microstructure of the CO2 corrosion scales formed under different conditions were investigated by means of SEM, EDS, XRD in this paper. A typical FeCO3 crystalline was observed in the scales of N80 (carbon steel) and lCr-L80 while chromium compounds were formed on the surface of 3Cr-L80 and 5G-L80. These chromium compounds were confirmed as Cr(OH)3 and Cr2O03. They were loose and formed chaps after dehydration. Under the static condition, the scales of carbon steel and chromium-containing...

The morphology and microstructure of the CO2 corrosion scales formed under different conditions were investigated by means of SEM, EDS, XRD in this paper. A typical FeCO3 crystalline was observed in the scales of N80 (carbon steel) and lCr-L80 while chromium compounds were formed on the surface of 3Cr-L80 and 5G-L80. These chromium compounds were confirmed as Cr(OH)3 and Cr2O03. They were loose and formed chaps after dehydration. Under the static condition, the scales of carbon steel and chromium-containing steels all had delamination structure. There were similar compositions between outer and inner scales of carbon steel in the form of (Fe, Ca)CO3. Chromium enrichment in the inner scales of chromium-containing steels was observed with the surface scale presented as (Fe, Ca)CO3. XRD patterns of the scales formed under dynamic condition indicated that the scales of chromium-containing steels gradually translated into amorphous structure with the increase of chromium content. The weight-loss testing results showed that the corrosion rate of chromium-containing steels approached to carbon steel under static condition, while under dynamic condition (1.5 m/s), the corrosion rates of chromium-containing steels were much less than that of carbon steel. And the corrosion rates decreased with the increase of chromium content.

研究了碳钢、低Cr钢在不同条件下形成CO2腐蚀产物膜的微观形貌、成分和结构特征.结果表明,N80(碳钢)、1Cr-L80形成的腐蚀产物膜主要由FeCO3晶体堆垛而成,而3Cr-L80、5Cr-L80的表层则形成大面积的含Cr化合物,主要为Cr(OH)3和Cr2O3.这些Cr的化合物脱水后比较疏松,容易形成龟裂,在静态条件下,碳钢和含Cr钢的腐蚀产物膜均具有分层结构,碳钢外层与内层腐蚀产物膜的成分变化不大,主要为Fe、Ca碳酸复盐.含Cr钢的内层腐蚀产物膜中出现Cr元素的富集,外层主要为Fe、Ca碳酸复盐.随着Cr含量的增加,材料的腐蚀产物膜向非晶态转变.在静态条件下,低Cr钢比碳钢的腐蚀速率稍大;在动态(1.5m/s)条件下,含Cr钢的腐蚀速率明显低于碳钢,而且腐蚀速率随着Cr含量的增加而下降.
