The semiconductor properties of passive film formed on 304L stainless steel (SS), 316L SS and Alloy 800HT in high-temperature and high-pressure water with zinc addition have been investigated by using Polarization curve, Mott-Schottky analysis and photocurrent method. The donor density, flat band and band gap of semiconductor behavior are analyzed to investigate the impact of zinc addition to the passive film. Analysis of the experimental results indicated that passive film formed on 316L and 800HT with zinc addition showed different electrochemical, photo-electrochemical and semiconductor properties. The results indicated that corrosion resistance of passive film from in high-temperature and high-pressure water with zinc addition was obviously better than that without zinc addition.

A new apparatus is described which enables continuous measurement to be made of the friction coefficient between surfaces sliding under boundary lubrication conditions in high-pressure (2700 lb/in2), high-temperature (up to 350°C) water environments. One specimen is held stationary under load against a moving specimen which may be either continuously rotated or reciprocated, linear rubbing speeds being low (of the order of a few centimetres per second). The design of the test section is such that any one of three geometrical configurations of specimen can be selected: piston-cylinder, journal-sleeve, or crossed-cylinders. The friction force transducers which have been developed for this work are described. Friction and wear results are presented for stainless steel (En 58E) sliding against itself, Inconel X, Nimonic 80A, chromium-plate and Deloro SF40, in the temperature range 20°-325°C.
