Investigation of wear and adhesion behaviors of borided steels
(Springer, 2016)
In this study, AISI P20, H13 and D2 steels were pack borided at 900 and 950 °C for retention times of 2, 4 and 6 h. The boride layer thickness values changed depending on the chemical composition of the steels. The hardness ...
Investigation of tribological behaviour of plasma paste boronized of AISI 8620, 52100 and 440C steels
(Niscair, 2011)
In the present study, AISI 8620, 52100 and 440C steels were plasma paste boronized (PPB) by using 100% borax paste. PPB process was carried out in a dc plasma system at temperature of 700 and 800 °C for 3 and 5 h in a gas ...

Corrosion and wear behaviors of boronized AISI 316L stainless steel
(Springer, 2013)
In this study, the effects of a boronizing treatment on the corrosion and wear behaviors of AISI 316L austenitic stainless steel (AISI 316L) were examined. The corrosion behavior of the boronized samples was studied via ...
Effects of alcohols on the corrosion of aluminum alloys in 1 N HCl solution. Part II
(Pleiades Publishing, Ltd, 2008)
The use of alcohols as cathodic inhibitors in HCl solution results in a negative shift of corrosion potential (Ecor). The alcohols concentration of 20 mM, was shown to be the best one. EDX analyses of the alloys showed ...
