Document Type and Number:
Japanese Patent JP2020164887
Kind Code:
A
Abstract:
To improve durability by improving wear resistance, by highly hardening a slide surface in a titanium alloy slide bearing.SOLUTION: In a slide surface 2 made of a recrystallized texture of a titanium alloy of a spherical slide bearing A made of a titanium alloy, primary α crystal grains and secondary α crystal grains are contained, in a dispersion state as a suppression phase of crystal grain growth, the primary α crystal grains are contained in the range of area rate of 1% or larger and smaller than 10%. By a "pinning effect" of the primary α crystal grains, secondary α crystal grains are miniaturized to heighten the hardness of a slide surface 2.SELECTED DRAWING: Figure 1
