Problems solved by technology

[0002] With the continuous improvement of science and technology, the production field is developing rapidly. At present, titanium alloy pipes are widely praised by various manufacturers due to their high physical properties. However, there are many kinds of titanium alloy materials mixed in the existing titanium alloy materials. Elements to adjust the physical properties of titanium alloys. The addition of molybdenum-nickel elements can improve the deformation resistance of alloy materials, but if the addition is too large, the hardness of the alloy finishing will decrease. Therefore, the current titanium-molybdenum-nickel alloys cannot be simultaneously Meet strong wear resistance and high hardness
