A method of forging a titanium alloy component comprises applying a protective coating onto the surface of the titanium alloy component. A glass lubricant coating is applied onto the protective coating and the titanium alloy component is forged at a high temperature. The glass lubricant coating comprises a borosilicate glass lubricant coating. The protective coating comprises an aluminide coating, a silicon modified aluminide coating, a platinum aluminide coating, an aluminium coating or a platinum coating. The titanium alloy component may be a compressor blade, or a compressor vane, of a high-pressure compressor of a gas turbine engine.
