HCMFM에 의한 자동차용 부품재료의 방식특성 = Anti-Corrosion Characteristics of Vehicle Component Materials against the HCMFM

다국어 초록 (Multilingual Abstract)

This study is concerned with the experimental effects of HCMFM(Highly Concentrated Methanol Fuel Mixture) and the anti-corrosion additives on the vehicle component materials.
Galvanized iron, SBR and viton were used as test materials. Experiments were carried out under the conditions of 25℃ and 10 rpm submerging test specimens into the HCMFM and the anti-corrosion additive containing HCMFM for 50 days.
Galvanized iron and viton showed anti-corrosiveness against M100 only without the change of exterior view and decrease of weight except M100A, M85, M85A and gasoline with local corrosion or decrease of luster. SBR was corroded against M100, M85 and gasoline with local corrosion, M100A and M85A with decolorization.
Hexamethylenetetramine showed the significant anti-corrosion effects on galvanized iron against M100A, viton against M100A and M85A.
Sebacic acid showed the significant anti-corrosion effects on SBR against M100A and adipic acid on SBR against M100A and M85A.
Triethylenetetramine showed insignificant anti-corrosion effects on all the test specimens against M100A and M85A with homogeneous, local corrosion or swelling.
DGOl-100 seems to be suitable anti-corrosion additive on galvanized iron against M85A, SBR against M85A, viton against M100A and M85A except galvanized iron against M100A and SBR against M100A with rust or local corrosion.
