Abstract

Purpose

The purpose of this paper is to investigate the silt erosion performance of Bare, 75%Cr₂O₃ + 25%Al₂O₃ and 85%Cr₂O₃ + 15Al₂O₃-coated SS304 under various control parameters such as rotation speed, concentration of silt and particle size of silt used for making slurry. This can provide insight for using chromia and alumina-based coatings for hydro-turbines.

Design/methodology/approach

Taguchi approach was used to identify the effect of three input parameters on the bare and coated alloys. L₁₆ orthogonal array is used for determining the signal-to-noise (S/N) ratio for each process parameter. For each level of parameters taken into consideration about the erosion wear, the arithmetic mean of the S/N ratio is calculated. On the essence of the results of S/N ratios, it is possible to determine the effect of the most dominating parameters of the erosion wear.

Findings

Results show that the erosion increases with an increase in silt concentration (Wt.%). It has been analyzed that the rotational speed has the most significant effect followed by the particle size and concentration on erosion wear for all uncoated and coated SS-304 samples. Maximum resistance to erosion is provided by 85%Cr₂O₃ + 15%Al₂O₃. The least erosion wear for process parameters has occurred at the optimal parametric combination of rotational speed (N) = 415 rev/min, concentration (C) = 15 Wt.% and particle size range as <53 µm for uncoated and coated stainless steel.

Originality/value

The study clearly shows the silt erosion performance of chromia and alumina coatings of different compositions at different input parameters.

操作参数对裸钢和涂覆 SS304 钢淤泥侵蚀性能的影响

目的本文旨在研究在各种控制参数（如转速、淤泥浓度和用于制作浆料的淤泥粒度）下，裸 SS304、75%Cr2O3 + 25%Al2O3 和 85%Cr2O3 + 15Al2O3 涂层 SS304 的淤泥侵蚀性能。设计/方法/途径采用田口方法确定三个输入参数对裸合金和涂层合金的影响。L16 正交阵列用于确定每个工艺参数的信噪比（S/N）。对于考虑到侵蚀磨损的每一级参数，都计算出信噪比的算术平均值。根据信噪比结果的实质，可以确定侵蚀磨损最主要参数的影响。研究结果表明，侵蚀随着淤泥浓度（重量百分比）的增加而增加。对所有未涂层和涂层 SS-304 样品进行分析后发现，转速对侵蚀磨损的影响最大，其次是粒度和浓度。85%Cr2O3 + 15%Al2O3 的抗侵蚀能力最强。在转速 (N) = 415 转/分钟、浓度 (C) = 15 Wt.%、粒度范围为 53 µm 的最佳参数组合下，未涂层和涂层不锈钢的工艺参数侵蚀磨损最小。
