Abstract
Korosi merupakan penurunan mutu material yang disebabkan oleh pengaruh lingkungan sekitarnya. Terbukti pengendalian korosi yang paling efektif dan ekonomis adalah coating. Metode pengaplikasian coating yang tepat juga dapat menyebabkan ikatan adhesi yang maksimal antara material coating dengan logam yang akan dilapisi, sehingga lapisan coating dapat memproteksi terhadap korosi dengan sempurna. Penelitian ini dilakukan untuk menganilis pengaruh metode pengaplikasian coating (kuas, roll, spray) pada pelat baja karbon rendah ASTM A36 terhadap prediksi laju korosi, kekuatan adhesi, dan ketahanan terhadap benturan. Hasil pengujian laju korosi menunjukkan metode spray terbaik dalam menahan laju korosi serendah mungkin yaitu dengan nilai laju korosi sebesar 0.00029799 mmpy. Dilanjutkan dengan metode kuas dan roll memiliki nilai laju korosi berturut-turut sebesar 0.00069233 mmpy dan 0.0043177 mmpy. Hasil pengujian kekuatan adhesi diperoleh hasil metode spray (sempot) memiliki nilai kekuatan daya lekat cat terbaik dengan rata-rata nilai 22.02 Mpa, sedangkan spesimen yang diaplikasikan coating menggunakan kuas dan roll memiliki nilai rata-rata kekuatan daya lekat cat sebesar 20.55 Mpa dan 18.13 Mpa. Hasil pengujian Impact spesimen yang diaplikasikan coating dengan menggunakan spray memiliki ketahanan terhadap benturan yang paling baik yaitu dengan ketahanan impact maksimum sebesar 4.25 Joule. Untuk spesimen yang diaplikasikan menggunakan kuas dan roll memiliki ketahanan impact sebesar 4.09 Joule dan 3.76 Joule. =============================================================================================
Corrosion is a material degradation that caused by the influence of the surrounding environment. It was proved, the most effective and economical of corrosion control is coating. Appropriate coating application methods can also cause maximum adhesion bonds between the coating material and the metal that be coated, so that the coating layer can protect against corrosion perfectly. This research was conducted to analyze the effect of coating application method (brush, roll, spray) on low carbon steel plate ASTM A36 to prediction of corrosion rate, adhesion strength, and resistance to impact. The result of corrosion rate test showed that the best method to applicate coating is spray which keeps the corrosion rate as low as possible with the corrosion rate, 0.00029799 mmpy. Followed by brush and roll method have the value of corrosion rate respectively 0.00069233 mmpy and 0.0043177 mmpy. The result of the adhesion test obtained by spray method has the best strength value method with the average value of 22.02 Mpa, whereas the specimen applied coating using brush and roll have mean value of paint attachment power of 20.55 Mpa and 18.13 Mpa. Test results of Impact test, the specimen which applied coating using spray have maximum impact resistance of 4.25 Joule. For specimens are applied using brushe and rool have impact resistance of 4.09 Joule and 3.76 Joule.
