Abstract
A spray tip configured to atomize a fluid comprises an inlet configured to receive the fluid; an outlet defining an exit from the spray tip; internal geometry defining a pathway from the inlet toward the outlet; and a manufactured wear-mimicking geometrical feature.
Claims19
A method of manufacturing a spray tip having a wear-mimicking geometrical feature, the method comprising:
- pressing carbide powder in a die to form an unfinished spray tip;
- providing an outlet in the unfinished spray tip;
- and
- removing material from an interior surface of the unfinished spray tip in an area surrounding an inner perimeter of the outlet to form the wear-mimicking geometrical feature extending along the interior surface of the unfinished spray tip and radially away from the inner perimeter of the outlet.

A method of manufacturing a spray tip, the method comprising:
- forming a die having geometry to form a spray tip having an inlet, internal geometry, an outlet, and a wear-mimicking geometrical feature extending along a surface of the internal geometry and radially away from an inner perimeter of the outlet;
- placing carbide powder in the die;
- pressing carbide powder in the die to form a compact;
- removing the compact from the die;
- and
- sintering the compact to form the spray tip having the inlet, the internal geometry, the outlet, and the wear-mimicking geometrical feature extending along the surface of the internal geometry and radially away from an inner perimeter of the outlet.
3 more elements
A method of manufacturing a spray tip, the method comprising:
- generating an unfinished spray tip having a first projected wear curve, the first projected wear curve comprising a first portion, corresponding to an initial use period, and a second portion, corresponding to a subsequent use period, the first portion less linear than the second portion;
- and
- finishing the unfinished spray tip to generate the spray tip by providing a wear-mimicking geometrical feature extending away from inner perimeter of an outlet of the spray tip and towards an interior of the spray tip, the spray tip having a second projected wear curve, the second projected wear curve more linear than the first projected wear curve.
