The present invention concerns a method for modifying the properties of the surface (F) of a material. The method comprises the following steps: preparing a first layer (12; 12) comprising an electrically conductive material suited to serve the function of a cathode, a second layer (14) comprising an electrically conductive material suited to serve the function of an anode and an intermediate layer (16) suited to become impregnated with an electrolyte in the liquid phase or to regulate its flow between said cathode and said anode; associating an electrolyte in the liquid phase with one or more of said layers (12, 14, 16); positioning the anode or the cathode on the surface (F) to be treated; supplying power to the cathode and the anode in order to activate the electrochemical process of the electrolyte in the liquid phase for a predetermined time interval.

In one aspect, an article comprises a substrate that comprises a ceramic matrix composite; and a metal oxide layer disposed on the substrate; where the metal oxide layer has a marking etched into the metal oxide via laser ablation. The markings include alphabets, numbers, symbols, bar codes, matrix bar codes, quick response codes, or a combination thereof. Disclosed herein too is a method comprising disposing upon a ceramic matrix composite a metal oxide layer; and laser ablating the metal oxide layer to etch the metal oxide layer. The etchings produce markings that comprise alphabets, numbers, symbols, bar codes, matrix bar codes, quick response codes, or a combination thereof.

A method for processing a component is provided and includes masking a first portion of the component with a maskant. The maskant includes a slurry having a plurality of particles in a fluid carrier. The plurality of particles comprises at least one of silicon, carbon, one or more rare earth disilicates, monosilicates or oxides, and combinations thereof. The method includes depositing a silicon-based coating on a second portion of the component via a chemical vapor deposition process and removing the maskant and any overlying silicon-based coating from the first portion of the component.

A preparation method includes the following steps: Step (1): pressing and then drying body powder to form a green brick; Step (2): applying a ground coat on the surface of the green brick; Step (3): inkjet-printing a pattern on the surface of the green brick having the ground coat, and applying an isolation glaze; Step (4): applying a fully polished glaze on the surface of the green brick having the isolation glaze; and Step (5): drying, firing, and polishing the green brick having the fully polished glaze to obtain a hard wear-resistant polished glazed ceramic tile. The phase composition of the fired fully polished glaze is as follows: 10 to 20 percent by weight of corundum, 20 to 30 percent by weight of hyalophane, 0.5 to 1.0 percent by weight of hematite, and 50 to 68 percent by weight of amorphous phase.
