"Magnesium (Mg) alloys are receiving increasing attention due to their abundance, light weight, castability, formability, mechanical properties and corrosion performance. By selecting the appropriate combination of materials, coatings and surface modifications, their corrosion resistance can be greatly enhanced. Corrosion prevention of magnesium alloys is a comprehensive guide to the effective prevention of corrosion in these important light metals.Part one discusses alloying, inhibition and prevention strategies for magnesium alloys as well as corrosion and prevention principles. Part two reviews surface treatment and conversion. Beginning with an overview of surface cleaning and pre-conditioning, the book goes on to discuss the use of surface processing and alloying, laser treatments, chemical conversion and electrochemical anodization to improve the corrosion resistance of magnesium alloys. Coatings are then the focus of part three, including varied plating techniques, cold spray coatings, gel and electroless electrophoresis coatings. Finally, the book concludes in part four with a selection of case studies investigating the application of preventative techniques for both automotive and medical applications."

"Magnesium alloy dapat digunakan sebagai implan biodegradable yang bersifat sementara untuk implan tulang dan vascular stents karena memiliki sifat biocompatible dan biodegradable. Tingkat kekakuan yang dimiliki oleh magnesium alloy juga dekat dengan tulang sehingga dapat mengurangi stress-shielding effect. Namun, magnesium alloy memiliki ketahanan korosi yang buruk apabila terkena kondisi lingkungan yang korosif sehingga akan menghasilkan laju korosi yang tinggi dan degradasi yang cepat sehingga akan menyebabkan kegagalan awal pada implan. Masalah tersebut dapat ditingkatkan dengan teknik pemrosesan yang tepat seperti perlakuan permukaan. Salah satu tekniknya adalah deposisi ZrO2 dan HA untuk meningkatkan ketahanan korosi implan magnesium alloy. Proses EPD dilakukan pada tegangan sel konstan 20 V selama 40 menit pada suhu kamar untuk masing-masing larutan ZrO2 dan HA. Hasil penelitian menunjukkan bahwa ketahanan korosi implan magnesium alloy yang dilapisi ZrO2 dan HA meningkat seiring meningkatnya kekerasan dan kekasaran implan magnesium alloy. Mikrostruktur permukaan pada ZK61 yang telah dilapisi oleh ZrO2 dan HA lebih seragam dan merata dibandingkan dengan mikrostuktur AZ31 yang telah dilapisi oleh material yang sama. Icorr optimum yang didapatkan pada ZK61 sebesar 3.02 μA/cm2 dengan laju korosi sebesar 0.15mm/year. Hasil ini juga menyebabkan penurunan laju degradasi magnesium implan setelah proses perendaman pada simulated body fluids

Magnesium Alloy can be used as temporary biodegradable implants such as bone implants and vascular stent due to its biocompatible and biodegradable properties. The level of stiffness possessed by magnesium alloys is also the closest to bone so that it can reduce the stress-shielding effect. However, Mg-alloy has poor corrosion resistance when exposed to severe conditions which will result in a high corrosion rate and rapid degradation will lead to the early failure of implant. Those issues can be enhanced by appropriate processing techniques such as surface treatment. One of the techniques is the deposition of ZrO2 and HA to enhance the corrosion resistance of magnesium implants. The electrophoretic deposition process conducted at a constant cell voltage of 20 V for 40 min at room temperature for each ZrO2 and HA. The results shows that the corrosion resistance of magnesium implant coated by ZrO2 and HA increase as hardness and the roughness of magnesium alloy implant increases. Microstructure of ZK61 surface after deposition shows that ZrO2 and HA successfully deposited and evenly distributed. ZrO2 and HA coated ZK61 exhibited significantly better corrosion resistance as compared to AZ31 with Icorr 3.02¼A/cm2 and corrosion rate 0.15mm/year, confirmed by the polarization test. This results also lead to the decreasing of degradation of magnesium implant after the immersion process on simulated body fluids."

"Dalam lingkungan bisnis modern, perusahaan yang sukses tidak dapat mentolerir kegagalan korosi, terutama yang melibatkan cedera pribadi, kematian, tidak terjadwal penutupan dan pencemaran lingkungan. Baja karbon merupakan material yang sangat banyak digunakan pada industri pertambangan, perminyakan dan petrokimia. Penggunaan baja karbon tersebut membutuhkan proteksi dari proses korosi. Penelitian ini dimaksudkan untuk pemanfaatan magnesium serbuk dengan proses penyerutan anoda korban yang sudah tidak terpakai untuk digunakan sebagai material campuran pada cat epoksi resin. Material dasar (substrat) yang digunakan adalah baja karbon rendah AISI SS400. Metode pengujian antara lain uji tarik, komposisi kimia, sembur garam (salt spray) ketebalan (DFT), EIS dan Polarisasi, SEM dan EDX. Ukuran serbuk kurang dari 177 µm. hasil pengamatan visual bahwa cat tampak lebih gelap tergantung dari jumlah serbuk yang ditambahkan, dikarenakan adanya penambahan viskositas dari cat epoksi. Nilai tarik cat dengan nilai paling besar yaitu sistem pengecatan 0g dengan nilai sebesar 7.8Mpa dan untuk ikatan adhesive-nya untuk semua bagus untuk semua jenis pengecatan, karena kegagalan cat masuk kategori kegagalan kohesif bukan pada substrat baja. Uji gores dan sembur garam dapat disimpulkan bahwa semua sistem pengecatan tidak terjadi pelebaran goresan. Pada pengamatan SEM dan EDX bahwa material serbuk magnesium hanya sedikit pada produk karat.Uji EIS menunjukkan bahwa sistem pengecatan 30g memiliki tahanan (Rct) yang paling tinggi dan hasil uji polarisasi sistem pengecatan 30g memiliki laju korosi paling kecil.

In the modern business environment, successful companies cannot tolerate corrosion failures, especially those involving personal injury, death, unscheduled shutdowns and environmental pollution. Carbon steel is a material that is widely used in the mining, petroleum and petrochemical industries. The use of carbon steel requires protection from the corrosion process. This research is intended to utilize magnesium powder by shaving the sacrificial anoda which is not used to be used as a mixed material in epoxy resin paint. The base material (substrate) used is AISI SS400 low carbon steel. Test methods include tensile test, chemical composition, thickness salt spray (DFT), EIS and Polarization, SEM and EDX. Powder size is less than 177 m. visual observation that the paint looks darker depending on the amount of powder added, due to the addition of the viscosity of the epoxy paint. The paint tensile value with the highest value is the 0g painting system with a value of 7.8Mpa and the adhesive bond for all is good for all types of painting, because paint failure is categorized as a cohesive failure not on a steel substrate. The scratch test and salt spray can be concluded that all painting systems do not occur scratch widening. On SEM and EDX observations, there was only a small amount of magnesium powder in the rust product. The EIS test showed that the 30g painting system had the highest resistance (Rct) and the 30g paint system polarization test results showed the lowest corrosion rate."
