“…Beyond Lc2, AE and COF signals remain more or less constant through the entire scratch length. It is noted that at applied load >11.5 N, the COF is ∼0.5 supports the previous scratch results of Cr-coated pins [26]. A number of small and narrow spikes are seen in AE signal, which may be associated with surface cracks at the edges.…”

Electroplated hard Cr-coated 17-4 PH stainless steel is regularly used in various parts of fuel handling system of nuclear reactors. In this study, the Cr-coated samples were investigated in detail for the coating adhesion using micro-scratch tester and ball indentation. Tribological investigation of the Cr coating was done in a reciprocating ball-on-plate dry sliding geometry against SS 440C ball counterbody. The wear and coefficient of friction (COF) tests were performed under five different loading conditions (3, 5, 7, 9 and 11 N) and three different sliding frequencies (5, 10 and 15 Hz). Wear scars on chromium coating were examined in detail by FESEM and 3D optical profilometer to understand the wear mechanism. It was observed that beyond 7 N critical load, the coating was prone to wear out drastically. Corrosion rate of the coating was estimated in 3.5 wt% NaCl solution by potentiodynamic experiment.

“…The high initial COF value for all conditions was due to the adhesion wear that occurred between the coated samples and the ball. Also, it is important to point out that the coefficient of friction values obtained in this study showed values lower than values obtained from Cr coatings by previous researchers [ [40] , [41] , [42] , [43] ], which invariably connotes better wear resistance. This signifies an improved adhesion of the electrodeposited Cr coating to the SS substrate, and this improvement could be attributed to the new pretreatment method (anodic activation) developed in this study.…”

“…Due to the widespread use of chromium in industrial processes, it is a major pollutant, among other toxic heavy metals. It is used mainly in electroplating [ 9 , 10 ], plating [ 11 ], and the manufacture of steel [ 12 ], tannery [ 13 , 14 ], and textiles [ 15 ]. Therefore, for these reasons there is a possibility that large amounts of chromium may enter the environment.…”

Immobilization of Hexavalent Chromium Using Self-Compacting Soil Technology

et al. 2022

A study of immobilization of hexavalent chromium in the form of Na2CrO4 salt by self-compacting soils (SCS) is presented. Carbofill E additive was used as SCS binder. The efficiency of immobilization of Cr (VI) was evaluated by washing out chromium compounds from SCS samples. The influence of the nature of the soil and the content of Carbofill E and Na2CrO4 in the SCS samples on the efficiency of Cr (VI) immobilization was studied. It was found that the nature of the soil and the content of Carbofill E in the SCS samples affect the immobilization of Cr (VI). Moreover, increasing the Carbofill E content in SCS samples further increases Cr (VI) immobilization. X-ray diffraction studies of the samples with immobilized hexavalent chromium showed that part of the sample transforms from a readily soluble form of salt into oxide forms of chromium and calcium-chromium, which are practically insoluble in water.
