Embodiment 1
[0040] This example includes the following steps:
[0041] Step 1: Pretreat the surface of the metal tungsten (W) substrate that needs surface strengthening, and prepare a multilayer film with niobium (Nb) / tantalum (Ta) by magnetron sputtering.
[0042] Step 1.1: Prepare a metal tungsten (W) plate with a purity of 99.9wt.%. Surface treat the tungsten plate, grind and polish it with sandpaper, and then clean it with acetone and alcohol in ultrasonic waves.
[0043] Step 1.2: Alternately deposit niobium (Nb) and tantalum (Ta) metal layers on the metal tungsten substrate by magnetron sputtering to form a Nb / Ta multilayer film, with a total of 30 layers and a total thickness of 30 microns.
[0044] Step 2: Carry out high-temperature heat treatment on the sample prepared with the multilayer film. The heat treatment temperature is 2000 degrees Celsius, and the heat treatment holding time is 0.5 hour. After the heat treatment, the sample is cooled to room temperature with the furnace...
