“…When the gas-flow rate was 500 mL/min and the maximum current value was 32 mA, the dissolution ratio of Ce increased logarithmically with the plasma-irradiation time. This tendency was confirmed by plasma oxidation and indicates that the diffusion length from the surface is limited (Fromhold Jr., 1982). The same tendency was observed in a previous study (Suzuki et al, 2005).…”

In this paper the glow discharge process is used for the deposition of ultrathin (d>10 nm) plasma polymers on iron specimens. The plasma polymer serves as an interfacial polymeric layer between the passive iron surface and a conventional pigment free water based 1‐component primer. Samples were fixed in the grounded electrode of an audio frequency discharge (4 kHz). Cleaning of the iron surface was achieved by an oxygen plasma treatment and plasma polymers were deposited from a mixture of hexamethyldisilane ((CH3)3Si‐Si(CH3)3) and argon. The modification of the surface structure was investigated by the use of quartz crystal microweighing (QCM) and infrared spectroscopy under grazing incidence (IRRAS) as in‐situ methods. Both the iron oxide as well as the plasma polymer are characterized in detail by infrared spectroscopy and photoelectron spectroscopy (XPS). The corrosion performance of primer coated samples was tested according to the kinetics of cathodic delamination which was measured in‐situ by the Scanning Kelvinprobe (SKP). While the pure oxygen plasma treatment, leading to a contamination free and thickened oxide layer, does not influence the delamination kinetics the existence of an only 5 nm thick plasma polymer at the metal‐primer interface leads to a significantly decreased rate of undermining.

“…Surface oxidation treatments including anodising and autoclaving, 9 thermal and plasma oxidation 10,11 and plasma electrolytic oxidation 12 have been researched to produce a protective oxide layer on zirconium alloys. However, the oxide film formed by anodising is too thin (,1 mm) to provide effective protection against mechanical damage whilst the thick oxide layer generated by plasma electrolytic oxidation is very rough and brittle.…”

“…However, the oxide film formed by anodising is too thin (,1 mm) to provide effective protection against mechanical damage whilst the thick oxide layer generated by plasma electrolytic oxidation is very rough and brittle. 10 Autoclaving can introduce a thick and dense oxide layer but it is a time consuming process and requires high pressures. 7 Plasma oxidation can increase the oxidation rate but of major concern is the detrimental effect of oxidation on the equipment used.…”

A series of ceramic conversion treatments have been conducted on Zr702 and Zr705 zirconium alloys by thermal oxidation at temperatures ranging from 400 to 700uC for 3-30 h. A wide range of material characterisation techniques were used to investigate the microstructure, composition, phase constituent, load bearing capacity and wear properties of the surface treated zirconium alloys. Experimental results show that after ceramic conversion treatments, the surfaces of Zr702 and Zr705 alloys can be converted to a ceramic layer consisting of a-ZrO 2 and b-ZrO 2 ; the optimal ceramic conversion treatment conditions for Zr702 and Zr705 alloys are 600uC/10 h and 600uC/ 3 h respectively; Zr705 alloy has a better response to ceramic conversion treatment than Zr702; and the wear resistance of the optimally treated zirconium alloys can be improved by more than 200 times. The wear mechanisms of both untreated and ceramic conversion treated zirconium alloys are discussed. The dominant wear mechanisms changed from severe adhesive wear for the untreated zirconium alloys to mild abrasive wear for the ceramic conversion treated materials.
