The invention provides a detection method for determining the surface quality of titanium alloy components after being subjected to vacuum heat treatment. The detection method comprises two steps of preparing standard sample pieces, contrasting and determining. The step of preparing the standard sample pieces comprises the following processes of firstly selecting eight titanium alloy component samples; then numbering the eight titanium alloy component samples; subsequently, putting the numbered titanium alloy component samples into an air furnace respectively for carrying out heat treatment, enabling different sample piece colors to correspond to different temperatures, and taking the titanium alloy component sample pieces subjected to heat treatment as the standard sample pieces; finally dividing the eight standard sample pieces to 1-8 grades according to the principle that the thicknesses of surface oxidation films are in one-to-one-correspondence with the surface colors; determining ...
