Glazing, edge wear, chatter marks and drifting thickness tolerances are the measurable signs a calender roll coating is finished. What each symptom means and when to regrind instead of recoat.
Why two quotes for the same drawing can differ by a factor of three. A breakdown of powder, spray time, masking, grinding and inspection cost - with a worked example and ways to reduce it.
Dielectric breakdown, edge flashover and mud-cracking account for most corona roller coating failures. Here is what causes each one and the spray, grind and sealing controls that prevent them.
Tungsten carbide and chromium carbide coatings look similar on a datasheet but fail differently. Compare hardness, service temperature, corrosion resistance and cost to pick the right one.
A practical comparison of HVOF and plasma spraying for wear parts: bond strength, porosity, temperature limits, coating thickness, materials and cost - plus the decision rules we use when quoting.
On February 24, 2025, 5 sets of Guangzhou Sanxin thermal spray equipment were exported to Kazakhstan for loading, including 2 sets of plasma spraying, two sets of SX-9000 supersonic spraying equipment, and one set of air supersonic spraying.
Guangzhou Sanxin Company's hydrogen production electrode net spraying production line is loaded into containers, and the spraying platform is loaded into special cabinets and shipped to South Korea.
