Summary:A variable gas turbine compressor vane structure includes a gas turbine compressor vane having a vane support at an end thereof, and a case structure having a bearing support disposed to engage the vane support of the gas turbine compressor vane. The bearing support is typically a bearing bushing or a bearing washer. The bearing support is made of a metal skeleton having open-cell porosity extending therethrough, and an infiltrant material such as an organic or a ceramic infiltrated into the porosity of the metal skeleton.
