“…Based on this hypothesis, there might be an optimum electropolishing time that yields the best glossiness improvement. In contrast with this prediction, increasing electropolishing time was claimed to continuously decrease surface roughness which reflects better glossiness of 316L SS under constant electric voltage [24] .…”

Electropolishing is an electrochemical surface finishing technique. It is commonly applied to equipment that requires a gleaming finish. This surface property is frequently required in 316L stainless steel (SS) medical implants. Electropolishing removes a thin layer from the metal's surface through electrochemical processes. This results in a very clean, smooth, and bright metal surface. The process parameters, such as electrolyte solution, electrical current, and electropolishing time, influence surface roughness and glossiness. The dissolution of metallic ions during the process may also affect the corrosion resistance of the treated material in addition to producing a shiny surface. This study investigated the surface glossiness, surface roughness, and corrosion of electropolished 316L SS. Electropolishing experiments on 316 SS were carried out using various H3PO4 (50%) and H2SO4 (32%) electrolyte solution compositions. The influences of electrolyte solution composition, electric current, and electropolishing time were studied. The results showed that increasing the H2SO4 content of the mixture and electropolishing the 316L SS for a longer period of time improved the surface roughness and glossiness. Under 10 Amp electric currents, the best surface glossiness was discovered. A corrosion test revealed that the electropolishing produced a Cr and Ni-rich layer that improved the corrosion resistance of the samples.

“…Ketahanan korosi material sangat dipengaruhi oleh kondisi permukaan dari material termasuk Stainless stell 316L walaupun Stainless steel 316L mempunyai mempunyai sifat yang superior untuk ketahanan korosinya [13,14,15]. Superioritas ini di karenakan adanya lapisan Chromium (Cr) pada stainless steel.…”

The waterjet pressure on the Abrasive Water Jet cutting processes affects all the related to the phenomenon of the material. In this study, the effect of water pressure on the AWJ process on the surface quality and corrosion properties of 316L Stainless steel was investigated. The cutting process is carried out by varying the pressure on the nozzle and with the cutting angle being kept at an angle of 90º to the substrate surface. In this research, Garnet with 200 mesh is used as the abrasive material. The results of the AWJ will be tested for corrosion using the 3-cell electrode method and then the surface topography will be observed using SEM. The results obtained in this study are that the corrosion rate decreases with increasing pressure in the AWJ process, however there is an increase after passing the optimal point, namely at 3500 Psi pressure.

“…Keuntungan yang dimiliki baja karbon rendah banyak dimanfaatkan produsen sebagai bahan dasar produk. Salah satu masalah penting dalam industri manufaktur adalah pengembangan teknik proses produksi yang menitikberatkan pada upaya mendapatkan suatu metode yang semakin efisien dan efektif namun dapat menghasilkan produk yang memenuhi ketentuan ketentuan standar mutu yang diterapkan (Widodo, 2019). Sehingga diperlukan pelapisan produk, dalam hal ini electroplating dinilai tepat diaplikasikan pada knalpot berbahan dasar baja karbon rendah.…”

Memperbaiki ketahanan korosi material dapat dilakukan dengan cara pelapisan logam. Tujuan utama electroplating adalah meningkatkan ketahanan korosi dan memperindah tampilan dengan variasi warna. Tujuan penelitian ini adalah meneliti pengaruh variasi warna pelapis terhadap laju korosi baja karbon rendah. Metode penelitian yang digunakan adalah eksperimen. Menggunakan proses zinc electroplating dan trivalent passivation treatment. Pengujian laju korosi menggunakan metode weight loss, masa perendaman 7 hari dengan medium korosif NaCl 3,5%. Pengujian ketebalan lapisan dilakukan menggunakan metode foto mikro. Hasil penelitian diperoleh dengan cara mengamati langsung hasil eksperimen yang disajikan dalam bentuk tabel dan grafik. Hasil penelitian menunjukkan terdapat pengaruh variasi warna pelapis terhadap laju korosi baja Baja AISI 1015 berupa penurunan laju korosi pada masing-masing variasi warna pelapis. Laju korosi terendah terdapat pada warna hitam yakni 0,016840030 mmpy. Ketebalan lapisan juga berpengaruh terhadap laju korosi baja Baja AISI 1015. Semakin tinggi ketebalan lapisan pada proses zinc electroplating maka semakin rendah laju korosi baja Baja AISI 1015.
