An investigation on the effect of cutting parameters in CNC plasma cutting process for carbon steel

The effect of technological parameters such as gas pressure, cutting current, standoff distance, and cutting speed on the cutting surface quality of CNC plasma cutting process was investigated. The experiment was carried out by Bruco CNC plasma cutting machine for CT3 steel with different thicknesses.

A study on the corrosive inhibition ability of CT3 steel in 1 M HCl solution by caffeine and some characteristics of the inhibition process

Caffeine was isolated from dry green tea leaves and used as corrosion inhibitor. The aim of this paper is to study the corrosion inhibition behavior of caffeine with its different concentrations (from 0.01 g/L to 3.00 g/L) for CT3 steel in 1M HCl solution by the curve polarization measurements and surface examination studies. Experiment result showed that: as the concentration of caffeine increases, the inhibition efficiency increases; %IE max is approximately 83.27% at concentration of caffeine 3.00 g/L.

Nghiên cứu khả năng chống ăn mòn của các hợp chất ancolamin và kaliiodua đối với thép CT3 trong môi trường axit HCL

The corrosion rate of the CT3 steel in 1 N and 2 N hydrochloric acids was measured by electrochemical polalization method. The measuring values of icorrosion showed that alcoholoamines influence on the inhibition corrosion of the CT3 steel in the hydrochloric acid solution and these values are increased in the order: monoethanolamine < diethanolamine < triethanolamine. In the solution of HCl 1 N and 2 N, the inhibition on the corrosion of steel CT3 of mixture of alcoholamines and potassium iodide is more effective than partial components.

Khảo sát khả năng ức chế ăn mòn thép CT3 của bốn dẫn xuất amit từ axit béo tổng hợp C8/C18

Inhibition ability of mild steel corrosion of 4 amides (RCONH2 (marked as A4), RCONH– CH2–CH2OH (marked as A5), RCON(CH2–CH2OH)2 (marked as 6b) and RCONH–(CH2)2–NH– COR (marked as 7c) prepared as derivatives from aliphatic acid oxidatively synthesized from nparaffin of Vietnam crude oil, has been examined by electrochemical methods. The corrosion test has been performed in chloride 3% solution at room temperature. The inhibition efficiency has been evaluated through corrosion potential Ecor, corrosion current icor and some other corrosion parameters.
