Critical diffusible hydrogen concentration for blistering of a micro-alloyed clean wheel steel
Journal Title: Science Paper Online - Year 2012, Vol 7, Issue 2
Abstract
The critical diffusible hydrogen concentration for hydrogen blistering of a micro-alloyed clean wheel steel was measured using the electrolytic hydrogen charging method. The results show that the diffusible hydrogen concentration and the density of hydrogen blisters on the sample surface increase with the hydrogen charging current density increasing. The lowest diffusible hydrogen concentration for blistering is 2.22×106. Setting the density of hydrogen blisters as 0.5 cm2≤ρ≤3 cm2 for the critical condition, the critical diffusible hydrogen concentration for producing the hydrogen blistering is (3.64± 0.55)×106.
