摘要： A method of applying heat shield material to form a heat shield layer on a crown surface of a piston of an engine is provided. The method includes the steps of disposing a dispenser that linearly discharges the heat shield material toward the crown surface, and moving an applied position of the heat shield material with respect to the crown surface in a circumferential direction of the crown surface, while discharging the heat shield material from the dispenser toward the crown surface.

摘要： A corrosion resistance test method for a coated metal material that includes a metal base and a surface treatment film, includes the steps of: disposing one or more water-containing material holders each holding a water-containing material to be in contact with the surface treatment film and one or more electrodes to be in contact with the water-containing material, and electrically connecting, with an external circuit, between the one electrode and the metal base, or between the electrodes; and supplying a current between the one electrode and the metal base, or between at least one of the electrodes and at least one of the other electrodes, as an anode and a cathode, to bring corrosion of the coated metal material to progress. The water-containing material comprises water, an electrolyte material, and kaolinite, and comprises the kaolinite at 36.0 mass % or more to 45.0 mass % or less.

摘要： A physical property evaluation method is the method for evaluating physical properties of a film-shaped measurement target object by means of an electrochemical method, the method including the step of causing an electrolytic solution to contact a front surface of the measurement target object. The speed of penetration of the electrolytic solution into the measurement target object is adjusted in such a manner that the levels of the front-side temperature and the back-side temperature of the measurement target object and a difference between the front-side temperature and the back-side temperature of the measurement target object are adjusted.

摘要： The method for a corrosion resistance test of a coated metal material is an electrochemical method simulating corrosion proceeded by damaged portions in the surface treatment film 4. Two artificially damaged portions 5 spaced from each other in a coated metal material 1 that is obtained by providing a surface treatment film 4 on a metal base 2 are electrically connected to each other by an external circuit 11 via an aqueous electrolyte material 6, and corrosion proceeds by supplying current using one of the artificially damaged portions 5 as an anode site and the other as a cathode site.

摘要： Provided is a measurement method for measuring a size of a damaged portion in a coated metal material that includes a metal base and surface treatment film provided on the metal base, and reaching the metal base through the surface treatment film. The measurement method includes the steps of disposing a water-containing material to be in contact with the damaged portion and an electrode to be in contact with the water-containing material, and electrically connecting between the electrode and the metal base with an external circuit; applying, with the external circuit, a constant voltage between the electrode and the metal base, as a cathode and an anode, respectively, and measuring a current value flowing therebetween; and calculating a size of the damaged portion, based on the current value measured and a correlation between the current value and the size of the damaged portion, determined on an exploratory basis in advance.
