Surface Treatments
Schivo’s surface treatments are applied to enhance the functionality, biocompatibility, corrosion resistance, and overall performance of medical components. These treatments are essential for orthopedic implants, hypodermic tubes, needles and cannulas, endoscopic devices, and surgical tools and instruments.
Schivo’s surface treatments include:
Powder coating: in our process, a dry powder (typically a polymer resin with pigments and additives) is electrostatically applied to a metal component and then cured under heat to form a smooth, durable coating. The process provides excellent wear, corrosion, and chemical resistance, is solvent-free, and has a fast-processing time.
PTFE spray coating: Schivo’s process applies polytetrafluoroethylene (PTFE), commonly known as Teflon®, onto medical components using a fine spray. The coating provides low friction, chemical resistance, and non-stick properties to the device. It helps reduce tissue adhesion and insertion force, enhances patient comfort, improves device performance, and lengthens device lifespan by reducing wear.
Electro-polishing: this critical surface finishing process enhances the cleanliness, corrosion resistance, and biocompatibility of metal components. Schivo smooths and brightens metal surfaces by removing a thin layer of material. Our process performs deburring and micro-finishing in one step to create an ultra-smooth finish that reduces friction and contamination.
Passivation: this important surface treatment is primarily used on stainless steel and other alloys to clean the component and enhance its corrosion resistance. Schivo’s process removes free iron and other contaminants from the metal surface and promotes the formation of a thin, protective oxide layer.
