Evaluating the effectiveness of anti-corrosion coating "Levikor" (Termishin) for parts of rail fasteners

The main type of damage to the operating parts of railway equipment is corrosion-fatigue fracture. In the period 2013 - 2014 specialists of JSC "VNIIZhT" conduct an integrated comparative study of the effect of thermal diffusion coating "Levikor" on the physical-mechanical and op...

description The main type of damage to the operating parts of railway equipment is corrosion-fatigue fracture. In the period 2013 - 2014 specialists of JSC "VNIIZhT" conduct an integrated comparative study of the effect of thermal diffusion coating "Levikor" on the physical-mechanical and operational characteristics of parts of rail fasteners (elastic clamps, clamp and embedded bolts, nuts). The aim of the test was to evaluate the effectiveness of the thermal diffusion zinc coating "Levikor" to protect against corrosion and extend the service life of parts of fasteners of the railway superstructure.Studies include laboratory and bench tests, static and cyclic tests of elastic clamps of rail fastenings ZhBR-65, clamp and embedded bolts and nuts after exposure to a corrosive environment in salt fog chamber and in operating terms. During the 13 months tested parts of the superstructure with the "Levikor" coating as part of KB65 fasteners were in operation in the Lysogorsky tunnel of the North-Caucasian railway, operating time was 30 million gross tons. Presented in the article comparative test results allow making the following conclusions:- KB65 fastening units with details with "Levikor" coating after being operated in Lysogorsky tunnel keep maintainability, whereas, in the absence of anti-corrosion coating fastening units are not repairable;- an increase was recorded in cyclic durability of clamps with anticorrosion coating "Levikor" under conditions of corrosive environment by 2.0 times and static strength by 1.4 times;- for areas with humid climate and increased atmospheric corrosion, expansion of the range of the upper parts of track superstructure, protected by coating "Levikor" is recommended as well as expansion of operational areas for its laying on the railway network of JSC "Russian Railways".
