【摘要】：對(duì)安裝與未安裝兩種形式口蓋鎖進(jìn)行了實(shí)驗(yàn)室加速腐蝕試驗(yàn),通過(guò)蝕坑深度和力矩差(松脫力矩與擰緊力矩的差值)研究了A286口蓋鎖的腐蝕行為,分析了裝配過(guò)程及裝配應(yīng)力對(duì)口蓋鎖腐蝕行為的影響。結(jié)果表明:安裝口蓋鎖的腐蝕程度明顯高于未安裝口蓋鎖的;未安裝口蓋鎖的主要腐蝕形式是接觸腐蝕,而安裝類(lèi)口蓋鎖的主要腐蝕形式是接觸腐蝕和應(yīng)力腐蝕;應(yīng)力腐蝕對(duì)口蓋鎖腐蝕的影響比接觸腐蝕的更大。
[Abstract]:The laboratory accelerated corrosion tests were carried out for both installed and uninstalled seal locks. The corrosion behavior of A286 cap locks was studied by the difference of pit depth and torque (the difference between loosening torque and tightening moment). The effect of assembly process and assembly stress on the corrosion behavior of the cap lock is analyzed. The results show that the corrosion degree of the installed lock is obviously higher than that of the uninstalled lock. Contact corrosion is the main corrosion form of the uninstalled cap lock, while contact corrosion and stress corrosion are the main corrosion forms of the installed cover lock. The effect of stress corrosion on lock corrosion is greater than contact corrosion.
