SLOTTED COATINGS AND METHODS OF FORMING THE SAME - A simplified explanation of the abstract

This abstract first appeared for US patent application 17806608 titled 'SLOTTED COATINGS AND METHODS OF FORMING THE SAME

Simplified Explanation

The abstract describes a method for forming a slot in a coated part, such as a ceramic coated part, using laser ablation. The method involves focusing a laser beam to a specific depth and irradiating the coating to remove material. The laser beam is scanned in a direction perpendicular to the coating's thickness, and each subsequent pass is deeper than the previous pass.

• The method involves laser ablation to form a slot in a coated part.
• The laser beam is focused to a specific depth and irradiates the coating to remove material.
• The laser beam is scanned in a direction perpendicular to the coating's thickness.
• Each subsequent pass of laser ablation is deeper than the previous pass.

Potential applications of this technology:

• Manufacturing of coated parts with slots, such as ceramic coated parts.
• Precision machining of coated parts with complex curvilinear shapes.

Problems solved by this technology:

• Traditional methods of forming slots in coated parts may damage the coating or result in imprecise cuts.
• Laser ablation allows for precise and controlled removal of coating material without damaging the part.

Benefits of this technology:

• Precise and controlled formation of slots in coated parts.
• Minimizes damage to the coating and the part itself.
• Enables the manufacturing of complex curvilinear parts with slots.

Original Abstract Submitted

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.
