Abstract
A method for fabricating a protonic ceramic energy device includes: coating an electrolyte layer on an anode layer; and densifying the electrolyte layer by a rapid laser reactive sintering (RLRS) process on the electrolyte layer and/or the anode layer to form a half-cell comprising a dense electrolyte and a porous anode.
Claims12
A method of forming a silica film, the method comprising:
- depositing silica sol-gel coating on a silica substrate;
- and
- sintering the coating by scanning the coating using a CO2 laser to form the silica film,
- wherein scanning the coating comprises scanning the coating at a fixed scanning speed of about 0.1 mm/sec and using a laser power density of about 0.7 W.
A method of 3D printing a component formed of fused silica glass, the method comprising:
- (a) depositing a first layer of fused silica paste based on a first 2D slice of a 3D model corresponding to the component;
- (b) melting the first layer of fused silica paste using a CO2 laser;
- (c) depositing a second layer of fused silica paste based on a second 2D slice of the 3D model corresponding to the component;
- (d) melting the second layer of fused silica paste using the CO2 laser;
- and
- (e) depositing and melting at least a third layer of fused silica paste to 3D print the component,
- the method further comprising increasing laser power during the melting steps to reduce the porosity of the component to thereby increase the transparency of the component.
A method of forming an optical fiber sensor, the method comprising:
- machining a microchannel in a ceramic substrate using a laser, the microchannel having a first portion having a first width and a second portion having a second width that is greater than the first width;
- receiving an optical fiber in the first portion of the microchannel;
- filling the second portion of the microchannel with a ceramic slurry to cover the optical fiber;
- preheating the slurry by scanning with a laser at a first power density and a first scanning speed;
- and
- sintering the slurry by scanning with the laser at a second power density that is greater than the first power density and at a second scanning speed that is slower than the first scanning speed.
A method of forming a fiber-optic sensor, the method comprising:
- 3D printing a housing on a diaphragm, the housing comprising a first cone-shaped portion and a second tubular portion on the first portion, the housing comprising a plurality of layers, wherein each layer is formed by extruding paste and irradiating the paste using a laser to melt the paste;
- coating an inner surface of the diaphragm;
- inserting a glass tube into the housing;
- filling a gap between the glass tube and the housing by inserting paste and melting the paste using a laser;
- inserting an optical fiber into the glass tube such that an end of the optical fiber is proximate the diaphragm;
- fixing the optical fiber in place using laser irradiation.
