invention relates to a deposition by pvd of an alloy called zircaloy 2 1 5 wt of tin 0 14 wt of iron 0 10 wt of chromium and 0 05 wt of nickel on stainless steel one face of this deposit underwent an extensive polishing close to optical polishing before the performance of tests in order to make it comparable with other cooking surfaces so that the tests for evaluation of the ease of cleaning such a surface in a domestic cooking use can be compared the system for evaluation of the ease of cleaning makes it possible to quantify the capabilities of a cooking surface to return to its original aspect after use this evaluation system comprises the following steps the surface is locally covered with a food mixture of known composition this mixture is carbonized in an oven under defined conditions for example 210 u00b0 c during 20 minutes after cooling surface is put to soak during a controlled time in a mixture of water and of detergent an abrasive pad is then applied under a defined constraint using an abrading apparatus plynometer on the soiled surface in a back and forth movement during a given number of cycles the percentage of correctly cleaned surface is noted and characterizes the ease of cleaning of the cooking surface the tests carried out on various types of surface thus make it possible to comparatively evaluate the quality of surfaces as to their ease of cleaning of course the tests are carried out by respecting the same parameters for each step of the evaluation system same food mixture same surface of application the food mixture same carbonization temperature the.
