Abstract:
This study investigated how boronizing affects the electrochemical corrosion behaviour of boronized carbon steel 1020 (0.049 wt.% C and 12.700 wt.% B) and stainless steel 304 (0.003 wt.% C and 8.940 wt.% B). Both materials were boronized using Borax powder at 900°C for eight hours, forming boride layers on their surfaces. [..]

Abstract:
The effectiveness of the protection of the base metal by the popular corrosion inhibitor BTA
(1,2,3-benzotriazole) depending on the method of application of the inhibitor was verified on lead coupons in an environment contaminated with acetic acid. The BTA inhibitor was applied alone or in combination with
a protective wax and/or varnish coating: a multi-layer system (BTA-single-layer wax/varnish, BTA-double-layer wax+varnish) or a BTA additive to the wax/varnish coating. [..]
