Would that be too redundant, and causing the intergranular corrosion and over-brittle? aarongoh3_1 https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1362250802 Select either one]]> 2021-03-29 00:12:17 UTC https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1362250802 Does nitriding cause sensitization because of the carbide formation? aarongoh3_1 https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1362252253 For a material that can be sensitised due to high temperature range, as long as heating occurs to that temperature range, the risk will happen. ]]> 2021-03-29 00:13:08 UTC https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1362252253 Electrochemical corrosion and intergranular corrosion are not correlated right? So the zinc-galvanizing approach won’t alleviates the corrosion cause by sensitization? aarongoh3_1 https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1362253990 One would choose austenitic stainless steel because of its shiny appearance. Defeats the purpose if the stainless steel is painted]]> 2021-03-29 00:14:04 UTC https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1362253990 Does the formation of carbide will certainly lead to intergranular corrosion? Or this corrosion only happens when a network of carbides are forming at the grain boundaries? I am quite confused, many resources say carbides improve wear and corrosion resistance, but what I learnt is carbides cause the corrosion. aarongoh3_1 https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1362257148 Sensitisation is due to C forming carbides with Chromium at the grain boundaries.  Otherwise carbide and sensitisation are two different things altogether. Carbides don't lead to corrosion in itself.]]> 2021-03-29 00:15:48 UTC https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1362257148 The intergranular corrosion is caused by every kind of carbide or it is only caused by chromium carbide? Because there are some types of carbides formed by molybdenum and tungsten which strengthen the metal instead of causing sensitization effect. aarongoh3_1 https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1362260044 Refer to answer above.]]> 2021-03-29 00:17:26 UTC https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1362260044 Prof, what was the coating again that is normally used to layer on top of bulldozer / crane blades? 20019815 https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1363336692 2021-03-29 09:02:06 UTC https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1363336692 Production method https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1364053217 2021-03-29 13:39:27 UTC https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1364053217 Update : I just realised that my previous contribution to answering your questions are now missing....No wonder you said I did not answer your questions - I did, but somehow they are now gone! aarongoh3_1 https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1364072045 2021-03-29 13:43:52 UTC https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1364072045 For Fun, was watching Big Hero in the weekend and Honey Lemon did an 'embrittlement' demo aarongoh3_1 https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1364111622 2021-03-29 13:52:52 UTC https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1364111622 Prof, where and how do we submit the project report? https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1364567013 2021-03-29 15:34:23 UTC https://padlet.com/aarongoh3_1/xkhpz3u6v5wb1wzp/wish/1364567013
