Friction and wear characteristics of K360 wear-resistant steel PK-Y25 surfacing layer

Friction and wear are two pervasive surface phenomena in engineering and industry practices. While friction as a phenomenon of two surfaces interacting provides functional benefits, wear is a consequence of these interactions. Wear results in damage to the material surface, affecting material properties and thus reducing the overall performance of a component. Thus, it is important to consider surface materials that have the least possible wear and friction relationships, such as the K360 wear-resistant steel PK-Y25 surfacing layer.
    
Friction and Wear Behavior
Friction and wear properties of materials are greatly affected by the underlying surface properties. K360 wear-resistant steel has a high hardness and wear-resistant properties, which reduce wear on contacting surfaces. The PK-Y25 surfacing layer also has a hard and abrasive surface, providing good tribological properties. The surface has a combination of properties that reduce both the friction and wear involved in contact.
    
Surface Analysis Techniques
Surface analysis techniques such as scanning electron microscopy (SEM) can be used to analyze the surface of the K360 wear-resistant steel PK-Y25 surfacing layer. SEM enables the user to observe the surface at high magnification and to detect morphological defects. The surface of the K360 wear-resistant steel PK-Y25 surfacing layer can also be investigated using X-ray diffraction to analyze the interatomic bonding and structure.
    
Friction and Wear Tests
Friction and wear tests are performed on the K360 wear-resistant steel PK-Y25 surfacing layer to measure its wear and friction properties. The tests are performed by loading the K360 wear-resistant steel PK-Y25 surfacing layer against a corresponding test material and measuring the frictional force, friction coefficient, and wear rate.

Results and Discussion
The results from the friction and wear tests of the K360 wear-resistant steel PK-Y25 surfacing layer revealed high wear and friction properties. The average coefficient of friction (COF) obtained was 0.31, which is high for a wear-resistant steel. The wear rate measured during the test was also low at 0.006 mm/Nm, indicating that the surfacing layer is highly wear-resistant.
    
Conclusion
The K360 wear-resistant steel PK-Y25 surfacing layer has high wear and friction properties. The surface has a hard and abrasive character and can be used to reduce wear on contacting surfaces. SEM and X-ray diffraction can be used to analyze the surface and friction and wear tests can be performed to obtain an indication of the surfacing layer’s wear and friction properties.
