High temperature corrosion of valve steels in combustion gases of petrol containing ethanol addition

Corrosion of martensitic stainless steel in ethanol-containing gasoline: Influence of contamination by chloride, H 2 O and acetic acid

“…A majority of these studies deals with corrosion of carbon steel or low-alloyed steels in fuel grade ethanol or in ethanol-gasoline blends [9][10][11][12][13][14][15][16]. Stress-corrosion cracking of carbon steel in ethanolic environments has been widely studied (see e.g.…”

The Influence of Yttrium on High Temperature Oxidation of Valve Steels

“…The combustion gases of petrol and fuel oil are highly aggressive and during last few years this corrosion danger considerably increased due to the addition to these fuels various bio-components [6][7][8][9][10][11][12][13][14]. In this situation, there is then an urgent need to improve the corrosion resistance of engine valves.…”

Influence of Nickel on the Oxidation Resistance at High Temperatures of Thin Chromium Coatings

“…During the above-described studies, the following question was asked: Are thin chromium coatings the optimal solution from the point of view of protection against corrosion, or should the chromium layers be enriched with another element that positively affects heat resistance by means of synergy? When analyzing this aspect, it should be noted that greater nickel content in chromium-containing valve steels has a beneficial influence on improving their heat resistance [14,15]. Thus, we should determine whether an analogous phenomenon can be observed in the case of thin coatings containing both chromium and nickel.…”
