Embodiment 1
[0033] This embodiment includes the following steps:
[0034] Step 1. Mechanical grinding: The first generation single crystal superalloy DD403 sample is subjected to rough grinding, fine grinding and mechanical polishing in sequence. The first generation single crystal superalloy DD403 is composed of the following components by mass: Cr 9.5% , Co5.0%, Mo 3.8%, W 5.2%, Al 5.9%, Ti 2.1%, the balance is Ni, the specific process is as follows:
[0035] Step 101, adopt 600 # The surface of the first-generation single-crystal superalloy DD403 sample is roughly ground with sandpaper until the surface of the first-generation single-crystal superalloy DD403 sample is smooth and free of dents;
[0036] Step 102, adopt 800 in turn # , 1000 # , 1500 # , 1800 # , 2000 # The first-generation single crystal superalloy DD403 sample after rough grinding in step 101 is finely ground with sandpaper until there are no visible scratches;
