ABOUT ZHENYU
HVOF thermal spraying forms bonding through mechanical interlocking with a bond strength of 50–80 MPa, featuring a lamellar stacking morphology. By contrast, our process achieves metallurgical bonding with a strength of 300 MPa. The coating blocks the penetration of high-temperature molten aluminum into coating interfaces, avoiding coating delamination and spalling under repeated thermal shock, as well as the contamination of castings by resultant debris. It overcomes the core limitation of HVOF coatings for plunger tip applications, delivering superior durability, near-zero porosity, low residual stress, ultra-low dilution rate, and crack-free surfaces.
For over 15 years, we have made business decisions based on the key factors of, what do customers in the field need and how can we exceed their requirements? Our commitment to better quality, competitive pricing, customer service has never failed our customers or Zhenyu.
LASER CLADDING
Laser cladding realizes the metallurgical bonding and the coating strength reaches 350MPa, which far exceeds the mechanical bonding of HVOF, because most of the powder is melted in space and absorbed more energy, the laser forms a shallower, smaller melt poor on the substrate material, resulting in ultra-fast cooling rates, this imparts more uniform microstructure to the coating, it helps to eliminate the brittle dendritic crystal structure, minimizes residual stress and reduces thermal impact on the substrate, small heat input, no dilution, no pores and no cracks.
ADDED VALUE
We have been supplying high quality castings for U.S government contractor Universal Technologies Inc.
