“…To obtain the sensitivity equations for MRR and Ra, Equations ( 1) and ( 2) are differentiated with respect to pressure. The sensitivity Equations ( 3)- (6) and Equations ( 7)- (10) represent the sensitivity of MRR and Ra for pressure, particle size, SOD, and flow rate, respectively. 𝜕(𝑀𝑅𝑅) 𝜕𝑝 = 0.0872 − 0.0121𝑝 − 0.043𝑆 + 0.00208𝐷 + 0.0057𝐹…”

The surface preparation of shiny stainless steels is a must for applying esthetic paints, effective functional plasma spray coating, laser cladding, welding, etc., applications. The current work aims for effective surface roughening and erosion MRR of SS 304 work surface using SiC abrasive jet erosion and optimization of the process parameters. The response surface approach is used to design and conduct the studies using the Box–Behnken design method. The surface topography of the eroded surfaces is examined by a 2D profilometer, 3D profilometer, and scanning electron microscope (SEM). The abrasive grit size and working gas pressure greatly affect the surface roughness of SS 304 samples. The influence of the process parameters on the variation of these topographical features is analyzed and confirmed. The working jet pressure is seen to significantly impact erosion MRR. The lower working gas pressure shows a typical influence on Ra (surface preparation) and as pressure increases, erosion MRR rises, and the surface preparation mode shifts to the erosion metal removal/cutting zone. The quality of SS 304 surface prepared from SiC abrasive jet impact is characterized by 3D profilometry.

“…Aplikasi cat bubuk banyak digunakan untuk komponen kendaran bermotor atau mesin, aluminium extruder sebagai bahan untuk fasad [9], [10], serta berbagai keperluan rumah tangga. Kualitas hasil pengecatan cat bubuk belum memiliki standar nasional sehingga masih mengacu pada standar yang berlaku di Eropa (qualicoat) dan Amerika [11].…”

Pengecatan menggunakan cat bubuk merupakan salah satu teknik perlindungan terhadap korosi yang berkembang secara pesat. Cat bubuk memiliki nilai estetika mendekati cat cair serta daya tahan dan utilisasi yang relative lebih baik dibanding cat cair. Proses pematangan cat bubuk yang hanya dilakukan dengan proses pemanasan pada suhu tertentu dan rentang waktu tertentu. Standard proses pematangan dikenal dengan kurva pematangan (curing map). Perbedaan suhu dan waktu terhadap rentang nilai standard menimbulkan resiko terjadinya perubahan warna khususnya pada warna putih (terang). Oleh sebab itu dilakukan penelitian untuk mengetahui pengaruh suhu dan waktu pemanasan terhadap kecenderungan menguning pada cat bubuk warna putih. Pengukuran warna dilakukan dengan menggunakan colorimeter dalam satuan CIE Lab. Nilai b pada CIE lab menunjukan kecenderungan warna kekuningan atau kebiruan. Suhu dan waktu pemanasan merupakan variabel penelitian yang faktornya ditentukan 5⁰C dan 5 menit diluar kurva pematangan. Kata kunci: cat bubuk, pematangan, suhu, warna.

Non-conventional machining processes are capable of achieving higher performance compared to conventional ones due to their inherent characteristics and higher amount of parameters which can be favorably regulated. Although the correlation between the most important process parameters and process outcome has been already established for a wide range of conditions and workpiece materials, the introduction of new considerations related to the three pillars of sustainability require further investigation on new means for the enhancement of AWJ milling process. As one of the most important parameters in AWJ milling is the abrasive material, the introduction of new materials may offer considerable advantages from different perspectives. Thus, in the present work, a comprehensive investigation on the efficiency of using eco-friendly, mixed abrasives is carried out under various conditions such as different traverse feed rate, abrasive mass flow rate, water jet pressure, jet impingement angle, and mixing ratio. The feasibility of using mixed abrasives is evaluated in terms of achievable depth of penetration, kerf width, kerf taper angle as well as material removal rate (MRR), and cutting efficiency. The findings indicate that among other factors, the mixing ratio plays a noticeable role especially regarding MRR and cutting efficiency and can offer an additional effective means to achieve the desired kerf characteristics in conjunction with other significant parameters such as water jet pressure.
