The invention provides a compact nanocrystalline tantalum coating with pressure stress prepared on the surface of titanium alloy and a method, according to the method, metal tantalum powder is used for conducting selective laser cladding on the surface of the titanium alloy under the remelting condition, the laser power of laser is 175-185 W, the thickness of each layer of metal tantalum powder on the surface of the titanium alloy is 10 micrometers, and the thickness of each layer of metal tantalum powder on the surface of the titanium alloy is 10 micrometers. The titanium alloy with the compact tantalum coating on the surface is obtained; and the titanium alloy with the compact tantalum coating on the surface is subjected to surface mechanical grinding treatment for 25-35 min through steel balls, and the compact nanocrystalline tantalum coating with the pressure stress is formed on the surface of the titanium alloy. The compact nanocrystalline tantalum coating has high bonding strength ...
