Publication number: 20230398635Abstract: A coated part, such as a ceramic coated part, having a slot formed in a coating formed on a curvilinear portion of the part and a method of forming the slot. The method includes performing a plurality of laser ablation passes. Each laser ablation pass includes focusing a laser beam to a focus depth, irradiating the coating of the curvilinear portion with the laser beam focused at the focus depth to remove coating material of the coating by laser ablation, and scanning the laser beam in a scanning direction while irradiating the coating of the curvilinear portion with the laser beam. The scanning direction is a direction transverse to a thickness direction of the coating. The focus depth of each subsequent pass of the plurality of laser ablation passes is deeper in a thickness direction of the coating than the pass preceding the subsequent pass.Type: ApplicationFiled: June 13, 2022Publication date: December 14, 2023Inventors: Hrishikesh Keshavan, Bernard P.

Patent number: 7892061Abstract: A hermetically sealed lamp having at least one seal-material-free bond. The seal material-free bond may be a material diffusion bond, a mechanically deformed bond such as a cold weld or crimp, a focused heat bond such as a laser bond, or any other such bond. For example, the hermetically sealed lamp may have one or more endcaps diffusion bonded to an arc envelope, such as a ceramic tube or bulb. The hermetically sealed lamp also may have one or more tubular structures, such as dosing tubes, which are mechanically closed via cold welding or crimping. Localized heating, such as the heat provided by an intense laser, also may be used to enhance any of the foregoing bonds.Type: GrantFiled: February 27, 2007Date of Patent: February 22, 2011Assignee: General Electric CompanyInventors: Bernard P.
