In this study we explore the cutting performance of ZrAlN coatings. WC:Co cutting inserts coated by cathodic arc evaporated Zr1-xAlxN coatings with x between 0 and 0.83 were tested in a longitudinal turning operation. The progress of wear was studied by optical microscopy and the used inserts were studied by electron microscopy. The cutting performance was correlated to the coating composition ...

Microbial fuel cells (MFCs) are a promising green approach for wastewater treatment with the simultaneous advantage of energy production. Among the various limiting factors, the cathodic limitation, with respect to performance and cost, is one of the main obstacles to the practical applications of MFCs. Despite the high performance of platinum and other metal-based cathodes, their practical use...

The high corrosion resistance of stainless steel (SS) reinforcing bars is widely recognized. However, little information is available on how much cathodic current a passive SS rebar assembly could produce to support a local anode as corrosion eventually starts. The ability of SS to perform as a cathode would have a direct impact on the corrosion rate of the anodic region. To address this issue,...

Indonesian Navy (TNI AL) is the main component for Maritime Security and Defence. Because of that, TNI AL needs Indonesian Warship (KRI) to covered Maritime area. The main requirement from KRI is fulfilled by demand. To pock of fuel demand from KRI at Naval Base, it needs a new pipeline of fuel distribution network system. The pipeline network system used for maximum lifetime must be protected ...

Cathodic activation examined with reference to the cold fuslon developments (controversy). Historically cathodic activation has been used for plating preparation of p a s s i v e (o x i d e) s u r f a c e s e.g. nickel/chromium alloys, niobium and powdered metals. More recent results of work employing cathodic activation for preparing aluminum for plating will be presented e.g. process paramete...

Organic solid wastes were treated in various types of methanogenic bioelectrochemical reactors, equipped with an external electrochemical system to control electron flow and improve microbial activity. At a high organic loading rate, cathodic bioelectrochemical reactors demonstrated greater decomposition of artificial garbage slurry and higher methane production than both anodic bioelectrochemi...

Steel pipelines are susceptible to corrosion by the action of corrosive substance in the environment and one of the most common failure modes in buried pipeline coatingis cathodic disbondment. Consequently, Electrochemical Impedance Spectroscopy (EIS) was used to assess the effect of three important parameters, the thickness of coating, the artificial defect ...

a selective and sensitive method for determination of cadmium and zinc is presented. the method is based on adsorptive accumulation of the complexes of cd (ii) and zn (ii) ions with 4-amiono-5-methyl-2,4-dihydro-3h-1,2,4-triazol-3-tion (mmtt) onto hanging mercury drop electrode (hmde), followed by reduction of the adsorbed species by voltammetric scan using differential pulse modulation. the li...
