essai en enceinte de corrosion à disque Explanation: le coupon métallique est placé dans un flacon fixé à un disque dans l'enceinte de test. Le flacon est rempli de liquide corrosif et d'inhibiteur de corrosion. "Comment valider la tenue à la corrosion d'une pièce métallique https://metalblog.ctif.com › 2018/01/29 › comment-vali... Résoudre un problème de corrosion nécessite le plus souvent de ... mener des essais au brouillard salin (BS) en enceinte de corrosion pour valider la ...

Reference: Wheel Test Reference information: The wheel test is performed by adding the corrosive fluids and inhibitor to a ~ 7-oz (~ 207 cm3)bottle with a metal coupon, purging with a corrosive gas, and capping the bottle [I]. The bottle is then agitated for a period of time by securing it to the circumference of a "wheel" and rotating it. In the high-temperature, high-pressure wheel test, autoclaves substitute for the conventional bottle and allow different partial pressures of corrosive gases, such as CO2 and H2S, to be used. The wheel test is best regarded as a screening test in a preliminary stage of inhibitor evaluation because it may discriminate poor inhibitors from good ones, but not necessarily the best inhibitor among several good ones [2]. There is no theoretical or hydrodynamic method to determine the flow patterns in a wheel test." https://www.uv.mx/personal/rorozco/files/2011/02/PART-5-67-E... |
