For the long-term service of X65/Incoloy 825 bimetallic composite pipe girth welds in H 2 S environment, corrosion damage behavior was investigated. Characterizations welded joints were conducted by OM, SEM, XRD, and EDS. The pitting corrosion’s 3D surface morphology NACE-B solution saturated with results show that composition segregation occurs welding process, Laves phase appears between dend...

A novel method to classify the aggressiveness of soil considering its physicochemical content and development new synthetic solutions for lab uses is proposed. The results showed that main criteria existing in literature corrosivity classification might cause misunderstandings about real aggressiveness. proposed aim cover a wide range found worldwide order refine assessment their characteristic...

Slippery Liquid Infused Porous Surfaces (SLIPS) are a relatively new and promising development in the surface engineering world. Bio-inspired with superior omniphobicity robustness, SLIPS have enjoyed success several scientific applications, spanning multiple industries from marine environment to medical field. Inorganic fouling is one such challenge managed overcome by disrupting both depositi...

Tingkah laku kakisan keluli karbon API 5L X65 dengan kehadiran bakteria penurun sulfat (SRB) dalam persekitaran CO2 adalah dikaji. Uji kaji yang dijalankan bagi meneliti tingkah ujian kehilangan berat dan analisis permukaan. Spesimen didedahkan kepada medium kawalan (tanpa konsortium bakteria) SRB selama 10 hari aliran gas berterusan. Biofilem, produk kedalaman lubang terhasil dicirikan mikrosk...
