Yüzey Modifikasyon Stratejileri ile Metal Yüzeylerde Korozyon Önleme

Öz

Bu çalışma, metal yüzeylerin korozyona karşı korunmasında kullanılan yüzey modifikasyon tekniklerini hem literatür taraması hem de deneysel uygulamalar aracılığıyla incelemektedir. Korozyon, metallerin çevresel etkilere maruz kalarak mekanik ve kimyasal özelliklerini kaybetmesine yol açan kritik bir problemdir. Literatürde yer alan kaplama, oksidasyon ve elektrokimyasal işlemler gibi yüzey modifikasyon yöntemleri, dayanıklılığı artırmada önemli katkılar sağlasa da maliyet ve uygulanabilirlik açısından sınırlılıklar taşımaktadır. Bu çalışmada, AISI 4140 çelik ve EN-AW-6061 alüminyum alaşımlarına farklı yüzey modifikasyon teknikleri uygulanmış ve ASTM B117 standardına uygun tuz püskürtme testi ile korozyon davranışları incelenmiştir. Sonuçlar, kaplama homojenliğinin ve yüzey hazırlığının korozyon direncinde kritik rol oynadığını, ayrıca alüminyumun doğal oksit tabakası sayesinde çeliğe kıyasla daha yüksek direnç gösterdiğini ortaya koymuştur. Bulgular, yüzey modifikasyonunun yalnızca koruyucu bir işlem değil, aynı zamanda malzeme seçimi ve tasarım süreçlerinin bütüncül bir parçası olarak değerlendirilmesi gerektiğini göstermektedir.

Corrosion Prevention on Metal Surfaces through Surface Modification Strategies

Öz

This study investigates surface modification techniques for protection metal surfaces against corrosion through both a comprehensive literature review and experimental analysis. Corrosion, defined as the degradation of metals under environmental influences, represents a critical engineering challenge leading to substantial economic losses worldwide. Surface modification methods such as coating, oxidation, and electrochemical treatments significantly improve durability but also pose limitations in terms of cost and applicability. In this work, AISI 4140 steel and EN-AW-6061 aluminum alloys were subjected to different surface modification techniques, and their corrosion behavior was evaluated using the ASTM B117 salt spray test. The results revealed that coating homogeneity and surface preparation play decisive roles in corrosion resistance, while aluminum demonstrates superior longterm protection due to its natural oxide film. Overall, the findings highlight that surface modification should not be regarded solely as a protective measure but as an integral part of material selection and holistic design strategies
