Abstract

The purpose of present study was to examine the erosion wear behaviour of Fe-Cr coating deposited on 316 L steel using HVOF coating technology. Chromium content was varied (0-15) wt. % in the step of 5 wt. %. The erosion wear test was performed on Air Jet Erosion Tester by choosing set of parameters as per steady state condition and Taguchi Orthogonal array L16. On adding 5 wt. % Cr, the mechanical properties such as hardness and fracture toughness were improved by 21% and 47% respectively. In steady-state wear conditions, specific wear rate was increased with the increase in impact velocity and slurry concentration. Taguchi design of experiment revealed a particular set of parameter for minimum erosion wear rate such as chromium content of 15 wt. %, impact velocity of 40 m/sec, impingement angle of 45° and slurry concentration of 8 gm/litre.

Fe-Cr合金涂层固相颗粒侵蚀行为研究

采用HVOF涂层技术，研究了316l钢表面Fe-Cr涂层的冲蚀磨损性能。铬含量在5 wt. %的台阶上变化(0 ~ 15 wt. %)。在射流冲蚀试验机上，根据稳态条件和田口正交阵列L16选取一组参数进行冲蚀磨损试验。添加5 wt. % Cr后，合金的硬度和断裂韧性分别提高了21%和47%。在稳态磨损条件下，比磨损率随冲击速度和料浆浓度的增加而增加。田口设计的实验结果表明，最小冲蚀磨损率的一组特定参数为:铬含量为15wt . %，冲击速度为40m /sec，冲击角为45°，料浆浓度为8gm /l。
