One-Stop Corrosion Testing – Salt Spray Chambers with Integrated Control Systems

Shanghai – TOBO GROUP, a pioneer in sustainable materials testing technology, is proud to launch the BioCorr Eco Salt Spray Tester—the first salt spray system engineered to simultaneously monitor corrosion and material degradation, addressing a critical gap for industries adopting biodegradable or recycled materials. Unlike traditional testers that only measure corrosion (ignoring how degradation impacts corrosion resistance, or vice versa), this platform tracks both processes in real time—essential for manufacturers of eco-friendly packaging, medical biodegradables, and sustainable automotive components, where material breakdown and corrosion must be balanced to meet performance and environmental goals.
At the core of the BioCorr Eco is its Dual-Corrosion-Degradation Monitoring Engine, which integrates two complementary measurement systems to capture a complete picture of material behavior. The corrosion module uses high-resolution electrochemical sensors to detect pitting, rust formation, and coating failure (standard for salt spray testing), while the degradation module employs precision weight-loss tracking (±0.001g) and water-soluble byproduct analysis to quantify how the material breaks down over time. For example, when testing a biodegradable magnesium alloy medical implant, the engine can distinguish between “corrosion-induced weight loss” (from salt exposure) and “biodegradation weight loss” (from material breakdown)—critical for ensuring the implant degrades at a safe rate without premature corrosion failure. The system also controls environmental conditions to mimic real-world degradation scenarios, such as adjusting humidity (50-90% RH) and temperature (25-40°C) to match soil, marine, or bodily fluid environments—settings traditional testers lack. A sustainable packaging firm testing PLA (polylactic acid)-metal composite films reported that the BioCorr Eco revealed a key insight: high humidity accelerated both PLA degradation and metal layer corrosion, prompting them to add a moisture barrier that preserved performance while maintaining biodegradability.
Complementing this engine is the Sustainable Material Test Library, a pre-loaded database of 100+ profiles for common eco-friendly materials and industry standards. It includes templates for biodegradable polymers (PLA, PBAT, PHA), compostable coatings, recycled metals (regenerated aluminum, post-consumer steel), and bio-based alloys (magnesium-zinc-calcium for medical use), each aligned with global sustainability standards like EN 13432 (compostable packaging), ISO 10993-13 (biodegradable medical devices), and ASTM D638 (mechanical properties of recycled plastics). The library also lets users create custom profiles—for instance, a “marine biodegradable component” profile that combines 3.5% NaCl (seawater salinity) with 85% RH and 30°C to simulate ocean conditions. A medical device manufacturer used the ISO 10993-13 template to test biodegradable sutures coated with a corrosion-resistant polymer, confirming that the suture degraded over 12 weeks (as required) while the coating prevented premature corrosion of the metal needle. A recycled aluminum producer leveraged the “post-consumer aluminum” profile to validate that their recycled alloy had corrosion resistance comparable to virgin aluminum—helping them secure a contract with an eco-conscious automotive brand.
Real-world applications across sustainable industries underscore the system’s value: An eco-friendly packaging company used the BioCorr Eco to test compostable food containers with metalized liners, ensuring the containers degraded within 180 days (per EN 13432) while the liner resisted corrosion from acidic foods. A medical tech startup validated biodegradable bone screws, using the dual-monitoring engine to confirm the screws maintained structural integrity for 8 weeks (enough for bone healing) before gradually degrading—with no excessive corrosion that could harm surrounding tissue. A automotive supplier testing recycled steel for electric vehicle frames used the system to show that the recycled material’s corrosion resistance met OEM standards, while the degradation tracking ruled out any residual contaminants from recycling that could accelerate breakdown.
“BioCorr Eco was built for the next era of materials—where ‘sustainable’ can’t mean ‘low-performance’,” said TOBO GROUP’s Sustainable Materials Testing Director. “Manufacturers using biodegradable or recycled materials don’t just need to test corrosion—they need to understand how corrosion and degradation work together. This system gives them that clarity, so they can build products that are good for the planet and reliable for users.”
