Powder Metallurgy Guides
A practical guide hub for engineers and sourcing teams comparing PM design rules, defect troubleshooting, heat treatment, surface finishing, and assembly methods.
Design & Planning
DFM for Powder Metallurgy
Start here for geometry, tolerance, and tooling rules before a PM program gets locked.
Sizing & Coining for PM Parts
Review when sizing or coining is the right route for tighter dimensions, better flatness, and localized density improvement.
Threading & Tapping PM Parts
Use this guide when threaded holes, inserts, and tapping reliability become important in porous metal parts.
PM Design Failures
Review representative design misses and the lessons that prevent scrap, delay, and avoidable rework.
Process Control
PM Defects Troubleshooting
Use a practical defect-by-defect reference for porosity, cracks, dimensional drift, warpage, and carbon issues.
PM Heat Treatment Guide
Compare carburizing, quenching, tempering, and distortion control before locking the thermal route.
Copper Infiltration for PM Parts
Review when infiltrated PM is worth the added process cost for density, sealing, and machinability improvement.
How to Reduce Noise in PM Gears
Use this guide when gear pitch, fit, lubrication, or surface condition is driving NVH complaints.
Finishing & Joining
PM Surface Treatment Selection
Compare steam treatment, nitriding, plating, coating, and pore sealing by environment and performance target.
PM Assembly Techniques
Review press fits, threads, brazing, adhesives, and weldability limits for PM components and assemblies.
Steam Treatment for PM Parts
Compare steam oxidation benefits, sealing impact, corrosion behavior, and where steam treatment fits versus plating or impregnation.
Deburring Methods for PM Parts
Compare tumbling, brushing, machining, and other edge-conditioning methods used after sintering.
Passivation for Stainless PM Parts
Review when passivation is enough for stainless PM and when electropolishing or another finish should be considered.
Wear Resistance Upgrades
See how alloy, density, heat treatment, and coatings can improve wear life in demanding PM applications.
