...Marcin Szczech; Wojciech Horak Purpose – The purpose of this publication is to determine the influence of selected factors on the durability and the tightness of ferrofluid seals working in water environments. Ferromagnetic fluid (FF) seals are one of the most common applications of magnetic...

.... And an experimental study on the performance of the face seal in the actual liquid oxygen turbopump was completed where low-viscosity water was selected as the seal fluid for the sake of safety. The paper aims to discuss these issues. Design/methodology/approach – Different performances of face seals under...

...Jian Wu; Rong Di Han Purpose The purpose of this paper is to develop water vapour as a new cooling and lubricating technique in drilling Ti6Al4V. Water vapor is an economical and eco‐friendly coolant and lubricant. However, it is necessary to study the drilling chip deformation, forces...

... quality and engine component performance. Design/methodology/approach The effect of change in optical properties (e.g. transparency, absorption, and refractive index) of engine lubricants caused by the introduction of contaminants, such as gasoline, coolant, and water, on the surface plasmon resonance...

...Jianhua Wang; Jinlong Li; Xiaobo Wang; Weimin Liu Purpose The purpose of this paper is to prepare water‐soluble TiO₂ nanoparticles and evaluate the tribological properties as additives in water. Design/methodology/approach Nanoparticles present excellent friction‐reducing...

...Marian Sulek; Tomasz Wasilewski; Malgorzata Zieba Purpose Modern cutting fluids often are real aqueous solutions of chemical compounds. That form of cutting fluid is simpler in preparation, as compared to emulsions and microemulsions. The water base is a good cooling medium of high‐ecological...

... of coolants and lubricants has led to this study on a new green machining technology with application of water vapor as coolants and lubricants in cutting Ni‐based superalloys and titanium alloy Ti‐6Al‐4V with uncoated carbide inserts (ISO Type K10). The purpose of this paper is to show that machining...

...Jian Fang; Yubin Sun; Yanqiu Xia; Weimin Liu Purpose The purpose of this paper is to understand the effect of base media on the tribological performance and tribochemistry of bismuth thiophosphate additive. Design/methodology/approach The oil‐water double soluble additive bismuth...

...Franc Majdic; Jozef Pezdirnik Purpose Environmental protection regulations are becoming increasingly strict. Using water instead of a hydraulic mineral or biodegradable oil in power‐control hydraulic systems is a very positive step towards complying with these regulations. Since water hydraulics...

...C. Iliev Purpose Testing of silicon nitride (Si₃N₄) or silicon carbide (SiC), sliding on itself in water, revealed that hydrodynamic lubrication can be obtained at low‐sliding velocity. The purpose of this paper is to study the performance of Si₃N₄...

...Liu Junyan; Han Rongdi; Zhang Li Purpose At the present time, green cutting has become the focus of attention in ecological and environmental protection. Water vapor is cheap, pollution‐free and eco‐friendly. Therefore, it is a good and economical coolant and lubricant. To find the discipline...

...Rongdi Han; Junyan Liu; Yongfeng Sun Purpose Nowadays, green cutting has become the focus because of its ecological problem and the necessary environment protection, so that the research on experimentation of green cutting with water vapor as coolant and lubricant is studied because water vapor...

... Explains and illustrates the problem of microbial infection of lubricants, fuels and water on board ship. Suggests preventive measures and some of the hazards to avoid. Warns about potential problems with biocides. © Company 1994 Bacteria Biocides Corrosion Fuels Lubricating oil...
