Ferritik paslanmaz çelikler birçok ortamda korozyona karşı oldukça dayanıklıdır. Bilindiği gibi bu dayanımı artırmanın birkaç farklı yolu vardır. Bunlardan bazıları ısıl işlem, alaşımlandırma, tasarım, inhibitör kullanımı yüzey kaplamalarıdır. Bu çalışmada, ferritik paslanmaz çelik alaşım yüzeyine plazma püskürtme kaplama yöntemi kullanılarak, CoMoCrSi tozu 600 A akım şiddetinde kaplanmıştır. Kaplamasız ve kaplama uygulanan numuneler üçlü elektrot sisteminde korozyon deneylerine tabi tutulmuştur. Tafel eğrilerinden korozyon hızı hesaplanmıştır. Sonuç olarak yapılan kaplamanın ferritik paslanmaz çeliğin korozyon direncini çok iyi artırdığı tespit edilmiştir.
