Abstract

Telah dilakukan penelitian ketahanan terhadap korosi pada baja karbon rendah yang telah mengalami pendeposisian ion nitrogen dengan menggunakan teknik nitro-karbonasi dan teknik plasma lucutan pijar korona. Baja karbon rendah yang telah mengalami teknik nitro-karbonasi dan nitridasi dengan teknik plasma lucutan pijar korona diuji ketahanannya terhadap korosi melalui sel tiga elektroda. Dari hasil pengukuran uji korosi menunjukkan bahwa untuk teknik nitro¬karbonasi pada suhu 900°C ternyata semakin korosif, sedangkan pada teknik plasma lucutan pijar korona baja tidak semakin korosif pada suhu 200°C. Hasil eksperiment menunjukkan bahwa pada suhu 200°C penurunan laju korosinya sebesar 21,40%. Pada teknik plasma lucutan pijar korona pada suhu 250°C tidak semakin korosif dengan menambah lama waktu pendeposisian. The research about corrosion-ressistant low carbon steel which implanted by nitrogen ions using nitro-carbonazing and plasma glow corona discharge techniques has been carried out. The low carbon steel which was treated by nitro-carbonazing and nitriding techniques by plasma glow corona discharge technique has tested corrosion-ressistant by sel tiga elektroda. The corrosion test was founded that the low carbon steel wich was treated by nitro-carbonizing on 900°C was more over corrosive, but by using plasma glow corona discharge technique steel was more uncorrosive on 200°C. The experiment result on 200°C with corrosion rate decrease was 21,40%. In plasma glow corona discharge technique on 250°C was more uncorrosive with adding the implant time.
