1. Features:
Effectively improved the corrosion resistance;
Effectively improved the eccentric wear resistance;
The amorphous tungsten alloy on the surface is of high strength
(the yield strength and tensile strength are both higher than 2Gpa)
and without cracks, which enable the fatigue life of sucker rods to
be greatly improved to work more than one million times in
corrosive environment!
Mechanical Property: The backing material meets API standards.
Wear
Resistance: Good, equivalent to that
of hard chromium layer. Tungsten Alloy Layer and Backing Material
Binding Force: According to GB/T********5 testing, the plating
layer does not crack or peel off.
Thickness of Tungsten Alloy
Layer:
****0μm
Wear and Corrosion Resistance Test: Having passed a variety of the wear and corrosion resistance tests carried out by Xian CNPC Tubular Goods Research Institute, Xian Maurer Petroleum Engineering Laboratory, and Quality Supervision and Inspection Center of Surface Covering Layer Products for Machinery Industry.
