Inspection of track bolts

  

Track bolt appearance quality requirements

  

The inspection of the appearance of track bolts is from the appearance, plating layer and other aspects.

  

Inspection of Track Bolt Coating Thickness

 

1. Measuring method: The amount used has micrometer, vernier caliper, plug gauge, etc.

 

2. Magnetic method: The magnetic method measures the thickness of the coating layer. It is a non-destructive measurement of the non-magnetic coating layer on a magnetic substrate by a magnetic thickness gauge.

  

3. Microscopy method: Microscopy method is called metallographic method. It is to enlarge the etched fastener on a metallographic microscope with micrometer eyepiece to measure the thickness of the coating on the section.

  

4. Chronofluid method

  

The timing liquid flow method is to inject a solution that can dissolve the coating on the local surface of the coating, and calculate the thickness of the coating according to the time required for the local coating to dissolve. There are plating method, anodic dissolution Coulomb method and so on.

  

Examination of adhesion strength of track bolt plating

  

There are many methods to evaluate the adhesion between the coating and the base metal, usually the following.

 

1. Friction polishing test;

 

2. file test;

  

3.Scratch method;

  

4.Bend test;

  

5. Thermal shock test;

  

6. Extrusion method.

  

Corrosion resistance inspection of track bolt plating

  

The test methods for corrosion resistance of coatings are: atmospheric exposure test; neutral salt spray test (NSS test); acetate salt spray test (ASS test), copper accelerated acetate spray test (CASS test); and corrosion paste corrosion test (CORR test) and solution drip corrosion test; immersion test, immersion corrosion test, etc.
