Abstract

Metode pengendalian korosi seperti coating, khususnya Thermal Spray Aluminium (TSA) dan Thermal Spray Zinc (TSZ) diterapkan sebagai pelindung fisik dan sacrificial anjungan lepas pantai. Variasi jenis material abrasif dan jenis metal wire dapat berpengaruh terhadap kualitas dan performa dari TSA serta TSZ. Penelitian ini dilakukan melalui ekperimen untuk mengetahui pengaruh variasi material abrasif dan jenis metal wire terhadap kekuatan adhesi, ketahanan bending, dan laju korosi hasil aplikasi TSA dan TSZ pada baja karbon ASTM A36. Penelitian ini menerapkan analisis berbasis eksperimen yang diuji melalui pull-off test, bending test, dan pengujian laju korosi sel tiga elektroda. Dilakukan pula pengamatan dengan Scanning Electron Microscope (SEM) untuk memvalidasi hubungan morfologi dengan performa coating. Adapun kesimpulan dari penelitian ini yaitu bahwa variasi jenis material abrasif dan jenis metal wire dapat memberikan pengaruh terhadap kekuatan adhesi dan ketahanan bending hasil aplikasi TSA dan TSZ coating pada baja karbon ASTM A36. Nilai rata-rata kekuatan adhesi tertinggi diperoleh spesimen coating TSA dengan material abrasif aluminium oxide dan metal wire Metallisation senilai 17,89 MPa. Nilai rata-rata kekuatan adhesi terendah diperoleh spesimen coating TSZ dengan material abrasif garnet dan metal wire Dura-Metal senilai 9,65 MPa. Hasil pengujian bending menunjukkan bahwa variasi yang dapat mengalami retak mayor hanya spesimen coating TSZ dengan material abrasif garnet dan metal wire Dura-Metal. Pengujian laju korosi menghasilkan pernyataan bahwa spesimen yang memiliki ketahanan korosi terbaik yaitu spesimen coating TSA dengan material abrasif aluminium oxide dan metal wire Metallisation dengan nilai laju korosi 0,002 mmpy, dan ketahanan terendah dimiliki oleh spesimen coating TSZ dengan material abrasif garnet dan metal wire Dura-Metal dengan nilai laju korosi 0,370 mmpy.

Corrosion control methods such as coating, specifically Thermal Spray Aluminium (TSA) and Thermal Spray Zinc (TSZ), are applied as physical and sacrificial protectors for offshore platforms. Variations in abrasive material types and metal wire can influence the quality and performance of TSA and TSZ. This research was conducted through experiments to determine the effects of variations in abrasive materials and metal wire types on adhesion strength, bending resistance, and corrosion rates of TSA and TSZ applications on ASTM A36 carbon steel. The study employed an experimental analysis tested through pull-off tests, bending tests, and corrosion rate testing using a three-electrode cell. Observations were also made using Scanning Electron Microscope (SEM) to validate the relationship between morphology and coating performance. The conclusion of this study indicates that variations in abrasive material types and metal wire types can significantly affect the adhesion strength and bending resistance of TSA and TSZ coatings on ASTM A36 carbon steel. The highest average adhesion strength was obtained from TSA coating specimens with aluminum oxide abrasive material and Metallisation metal wire, measuring 17.89 MPa. Conversely, the lowest average adhesion strength was found in TSZ coating specimens with garnet abrasive material and Dura-Metal wire, measuring 9.65 MPa. Bending test results showed that only the TSZ coating specimens with garnet abrasive material and Dura-Metal wire experienced major cracking. Corrosion rate testing revealed that the specimen with the best corrosion resistance was the TSA coating with aluminum oxide abrasive material and Metallisation wire, exhibiting a corrosion rate of 0.002 mmpy. In contrast, the lowest resistance was found in the TSZ coating with garnet abrasive material and Dura-Metal wire, which had a corrosion rate of 0.370 mmpy.
