Characteristics of Cobalt based powder: Cobalt-based alloy powder is a material composed mainly of Cobalt and some other alloys. Cobalt-based alloy powders are known for their excellent corrosion resistance, oxidation resistance and durability. They are often used in high temperature environments due to their superior heat resistance. Apply for different technology: – HVOF / HVAF – Plasma Transfer Arc (PTA) – Laser Cladding Popular types of Cobalt based alloy powder: – Stellite 6 – Stellite 12 – Stellite 21 Co C Si Fe Cr Ni Mo W Typical HRC Typical Hv PD Co-35 (Stellite 21) Bal. 0,25 1,0 1,5 27,0 2,8 5,5 35 340 • Used as buffer layer • Work hardening alloy PD Co-41 (Stellite 6) Bal. 1,1 1,0 1,5 28,5 1,5 – 4,4 41 400 • All-rounder to combat corrosion, galling, erosion, cavitation or mechanical wear PD Co-44 (Stellite 12) Bal. 1,4 1,1 1,0 28,5 1,5 – 8,0 44 440 • Increased abrasion, corrosion and sliding wear resistance, higher high-temperature hardness PD Co-56 (Stellite 1) Bal. 2,4 1,1 — 30,0 — – 12,5 56 620 • High abrasion and corrosion resistance • Ideal for pump sleeves, rotary seal rings, wear pads, expeller screws and bearing sleeves • Thermal stability of hardness up to 760°C PD Co-53 (T-400) Bal.
