"Engineers are faced with a bewildering array of choices when selecting a surface treatment for a specific corrosion or wear application. This book provides practical information to help them select the best possible treatment. An entire chapter is devoted to process comparisons, and dozens of useful tables and figures compare surface treatment thickness and hardness ranges; abrasion and corrosion resistance; processing time, temperature, and pressure; costs; distortion tendencies; and other critical process factors and coating characteristics. The chapter 'Practical Guidelines for Surface Engineering' describes hands-on approaches for matching surface treatments with design and performance requirements. The book includes the content from an Institute of Materials design guide publication, combined with information from several ASM Handbook volumes and other ASM and industry sources. All the material has been carefully organized, edited, and rewritten as needed to provide a comprehensive, up-to-date, and user-friendly guide to the subject. "

"This book summarizes the results of years of research on the problem of strength and fracture of polymers and elastomers. It sets out the modern approach to the strength theory from the standpoint of fractals, the kinetic and thermodynamic theories as well as the meso-mechanic destruction. The dimension reduction method is applied to model the friction processes in elastomers subjected to the complex dynamic loading. Finally, it analyses a relation between the fracture mechanism and the relation phenomena, and provides new experimental data on the sealing nodes in accordance with their specific working conditions where the effect of self-sealing is observed."

"Friction stir welding merupakan jenis pengelasan solid state dengan memanfaatkan gesekan dari tool yang berputar sebagai sumber panas untuk menyambung logam. Selain metode pengelasan ini tidak memerlukan logam pengisi dan gas pelindung, metode ini efektif untuk mengelas logam berbeda, salah satunya adalah antara aluminium dengan tembaga yang akan sangat berguna untuk aplikasi komponen listrik. Friction stir welding pada penelitian ini diaplikasikan untuk mengelas aluminium 6061 dengan tembaga murni menggunakan variasi kecepatan putar tool sebesar 600, 1000, 1200, 2000 rpm. Perbedaan kecepatan putar tool tersebut diberikan untuk mengetahui pengaruhnya terhadap makrostruktur, mikrostruktur, konduktivitas listrik, dan kekerasan sambungan. Mikrostruktur diamati menggunakan mikroskop optik. Uji konduktivitas listrik dilakukan menggunakan alat uji mikro ohmmeter dan pengujian kekerasan dilakukan menggunakan alat uji mikro-vickers. Hasil penelitian memperlihatkan bahwa semakin besar kecepatan putar tool, masukan panas yang terjadi semakin meningkat sehingga cacat void yang terbentuk semakin sedikit. Masukan panas yang semakin meningkat juga menghasilkan nilai konduktivitas listrik sambungan menurun. Selain itu, nilai kekerasan sambungan meningkat seiring dengan meningkatnya kecepatan putar tool. Hal ini terjadi akibat semakin banyaknya senyawa intermetalik yang terbentuk.

Friction stir welding is a solid-state welding method that utilizes friction from a rotating tool that becomes a heat source for joining the metals. Besides this welding method does not require filler metal and gas shielding, it is effective for welding dissimilar metals such as aluminium and copper which would be very useful in electrical components applications. Friction stir welding in this research was used for joining aluminium 6061 to pure copper using various tool rotational speed of 600, 1000, 1200, and 2000 rpm. Those different tool rotational speed was given to determine its effect on macrostructure, microstructure, electrical conductivity, and joints hardness. The microstructure was observed using an optical microscope. The electrical conductivity test was carried out using a micro ohmmeter and the hardness test was carried out using a microhardness vickers testing machine. The results shows that the higher the tool rotational speed applied, the higher heat input gained, so that fewer voids were formed. The increasing heat input also made the electrical conductivity value of the joints decreased. Besides that, the joints hardness value increased with the increasing tool rotational speed. It occurred because more intermetallic compounds formed."

"Teknologi pada era industri 4.0 menuntut kebutuhan akan perangkat teknologi yang semakin canggih namun dengan berat yang semakin ringan dan ukuran yang lebih kecil. Untuk memenuhi kebutuhan tersebut, proses manufaktur berkembang kearah pembuatan komponen elektronik mikro yang diproduksi dengan teknik fabrikasi mikro (Microforming). Komponen dalam proses microforming yang paling berpengaruh yaitu cetakan (dies), dimana gesekan antarmuka antara permukaan cetakan dengan benda kerja dapat berpengaruh terhadap hasil produk akhir serta dapat memperpendek umur pakai cetakan. Untuk mengatasi masalah ini dapat diberikan pelapisan permukaan cetakan dengan diamond-like carbon (DLC). Studi literatur ini mempelajari pelapisan DLC pada permukaan cetakan microforming dengan membandingkan data penelitian terhadap koefisien friksi dan laju keausan. Hasil perbandingan pelapisan DLC dengan teknik physical vapour deposition (PVD) pada permukaan cetakan baja AISI D2 menghasilkan pengurangan nilai koefisien friksi hingga 50% dan penurunan laju keausan sebesar 2-6 kali lipat lebih kecil. Variasi penambahan gas Ne ke dalam gas Ar pada proses pelapisan DLC menghasilkan pengurangan koefisien friksi beserta laju keausan. Ketahanan aus lapisan DLC menunjukkan nilai koefisien friksi dan laju keausan terendah bila dibandingkan lapisan tahan aus lain.

Technology in the industrial era 4.0 demands the need for increasingly sophisticated technological devices but with lighter weight and smaller sizes. To meet these needs, the manufacturing process has been developing towards the manufacture of micro-electronic components which are manufactured using micro fabrication techniques (Microforming). The component in microforming process that has the most influence is the die, where the interface friction between the surface of the die and the workpiece can affect the final product and shorten the life cycle of the die. In this literature review, the DLC coating on the surface of the microforming die will be studied by comparing research data on the friction coefficient and wear rate. The comparison results of DLC coating with physical vapour deposition (PVD) techniques on the die surface, namely AISI D2 steel, have shown a reduction in the friction coefficient value of up to 50% and a decrease in wear rate of 2-6 times smaller. Then the variation with the addition of Ne gas into Ar gas in the DLC coating process obtained a reduction in the friction coefficient along with the wear rate. Finally, the wear resistance of the DLC coating is compared with other wear-resistant coatings, the lowest friction coefficient and wear rate were found in the DLC coating when compared to others."
