【摘要】：以TWIP鋼為研究對象,在不同露點和溫度下進行退火-鍍鋅試驗,采用FE-SEM、EDS能譜儀和EPMA對退火試樣進行分析,并與鍍鋅效果對照,得到退火氣氛對可鍍性的影響。試驗結果表明:在兩種退火溫度下,露點為-50℃時,氧勢低,極少量的Mn發(fā)生外氧化,熱鍍鋅效果較好;隨著露點升高,氧勢升高,表面生成更多膜狀和顆粒狀Mn的氧化物,可鍍性變差;而氧勢足夠高時,致使部分Mn發(fā)生內氧化,表面覆蓋少量的塊狀Mn的氧化物,且有Al的氧化物出現(xiàn),鍍鋅效果最好。
[Abstract]:Taking TWIP steel as the research object, the annealing galvanizing test was carried out at different dew points and temperatures. The annealed samples were analyzed by FE-SEMU EDS and EPMA, and compared with the galvanizing effect, the effect of annealing atmosphere on the plating property was obtained. The experimental results show that at two annealing temperatures, the oxygen potential is low and a very small amount of mn is oxidized out of the surface at -50 鈩，
