Corrosion Control Performance Evaluation of Acceptable Alternatives for Cadmium
نویسندگان
چکیده
Cadmium has been identified as a threat to worker health and the environment. A test program was conducted to evaluate the performance of environmentally acceptable substitutes for cadmium plating. Fifteen test coatings were exposed to natural marine, industrial, and rural atmospheres for 12 -months. Additional laboratory tests were conducted to determine coating abrasion resistance, adhesion, fastener breaking torque , electrochemical behavior, and resistance to stress corrosion cracking. The relative merits and limitations associated with the alternative cadmium substitutes are discussed.

Inhibiting effect of seed extract of Abrus precatorius on corrosion of aluminium in sodium hydroxide
Economic losses due to corrosion are direct, as well as, indirect and affect the economy of country. Corrosion inhibitors are one of the widely used methods to control corrosion. Particular advantage of corrosion inhibitor is that often can be implemented or changed in situation without disturbing a process. Due to toxic nature and high cost of some inhibitors currently in use it is nearly to d...
متن کاملTheoretical study for evaluation of corrosion inhibition performance of two thiocarbohydrazide inhibitors
Molecular dynamics (MD) simulation and Density functional theory (DFT) methods were applied to the two thiocarbohydrazides derivatives (T1 and T2) as corrosion inhibitors for carbon steel in aqueous phase. Experimental results have shown that the corrosion rate follows the below order: T1>T2. Quantum chemical parameters such as hardness (η), electrophilicity (ω),polarizability (α), dipole momen...
