RELATIVE EFFECTIVENESS OF VARIOUS TYPES OF CHROMIUM COATINGS conclusions Dense chromium coating after knurling possesses good antifriction properties. Dense coating after knurling has high wear resistance and wears off little of the surface conjugated with it. Dense coating protects the detail against corrosion. The process of dense chromium plating after knurling is technology simple, while the process of porous chromium plating is carried out by a strictly definite regime and the slightest deviations from same lead to a reduction in antifriction and wear resistant properties of the given coating. High energy ignition system for starting a gas turbine engine Conclusions To improve starting characteristics of a gas turbine engine it is advisable to use a low voltage ignition system of high energy capacitance type 10-12 joules. The use in the Rotaks ignition system of additional throttle inductance allows to increase the time of flow through of the discharge current through the spark plug and to improve the ignitability of the discharge.
