【摘要】：探討了TC1鈦合金腐蝕加工速度和質(zhì)量的影響因素,測(cè)試了腐蝕加工后TC1鈦合金的力學(xué)性能。氫氟酸濃度增加,加工速度提高;硝酸濃度較低時(shí),腐蝕溶解占主導(dǎo)地位,濃度較高時(shí),鈍化起主要作用,當(dāng)硝酸與氫氟酸的體積比為2時(shí)加工速度達(dá)到最大值;鈦合金腐蝕加工速率與溫度基本呈線性關(guān)系,加工時(shí)溫度控制范圍為28~30℃。復(fù)配添加劑可降低界面張力,它們的協(xié)同效應(yīng)能夠提高過(guò)渡區(qū)圓角質(zhì)量、表面光亮度和腐蝕均勻性。腐蝕加工對(duì)TC1鈦合金拉伸性能影響較小。腐蝕加工后的疲勞性能優(yōu)于機(jī)械加工后的疲勞性能,其疲勞裂紋起源于加工面R圓角根部區(qū)域。
[Abstract]:The influence factors of corrosion processing speed and quality of TC1 titanium alloy were discussed, and the mechanical properties of TC1 titanium alloy after corrosion processing were tested. When the concentration of hydrofluoric acid increased, the processing speed increased, and when the concentration of nitric acid was low, corrosion and dissolution dominated, and when the concentration was higher, passivation played a major role, and the processing speed reached the maximum when the volume ratio of nitric acid to hydrofluoric acid was 2. The corrosion rate of titanium alloy is linearly related to temperature, and the temperature control range is 2830 鈩，
