Abstract
A component for a gas turbine engine includes an airfoil section including a free end and an abrasive coating sprayed onto the free end, the abrasive coating including a polymer matrix and an abrasive filler, the abrasive filler between about 50%-75% by volume of the abrasive coating.
Claims7
A method of fabricating an abrasive coating on a component, comprising:
- spraying a polymer matrix which is atomized and propelled by an air jet toward the component;
- and
- communicating grit particles into the air jet such that the grit particles are entrained by the air jet and codeposited together with the polymer matrix onto the component, thereby forming an abrasive coating on the component with the grit particles bonded to the component;
- and further comprising curing the polymer matrix such that the polymer matrix outgases through the grit particles during curing.
