Cobalt/Chromium Carbide Composite Coatings Applied By Brush Plating For Use As An Alternative To Hard Chrome

Cobalt/Chromium Carbide Composite Coatings Applied by Brush Plating for Use as an Alternative to Hard Chrome
Available for download

In the war on corrosion and wear, maintenance repair engineers will be hard pressed to find a plating material as strong as chrome. It has high hardness, high lubricity, low wear resistance, and maintains some of its hardness even after being exposed to high temperatures.  However, there’s increasing pressure to find an alternative to this material due to the worker safety and environmental issues it presents.  Regularly, hard chrome is electroplated where it is needed using a plating solution containing chromium trioxide.  Chromium trioxide is registered with both REACH(1) and the EPA(2) as carcinogenic, mutagenic, and teratogenic.

Due to increased concern for both environmental and worker safety from governments around the world, many significant industrial chemicals are being phased out of production processes. One example is the use of hexavalent chromium compounds for the electrodeposition of hard chrome. Electrodeposited chrome is typically used for improved hardness, lubricity, wear resistance, and corrosion resistance. This work will support the use of a metal matrix composite composed of cobalt and chromium carbide particles as an alternative for chrome coatings deposited from hexavalent chromium compounds.

Geothermal Energy is currently engineered as an “always on” baseload supply, due to the limited flexibility to throttle the well without scaling and fatigue issues, and it is engineered for maximal efficiency at this output level. Scaling is a major problem in geothermal plants, particularly in cases where the geothermal fluid composition and plant operation make it difficult to control scaling. In such areas, particularly where scale inhibitors cannot be employed, the formation of scales can make the process less efficient and in extreme cases can lead to unexpected shutdown.

Environmentally Assisted Cracking (EAC) of gas transmission lines constitute about 2.6% of the total number of significant incidents recorded in the U.S. Pipeline and Hazardous Materials Administration (PHMSA) database [1]. For the hydrocarbon liquid pipelines, the EAC-related incidents constitute about 1%. Although Stress Corrosion Cracking (SCC) incidents are a relatively small percentage of significant incidents, it is important to predict the location and rate of growth of SCC because of the potential for catastrophic consequences from the growth of undetected cracks.

UNS N08935 is a new versatile super austenitic alloy with extreme pitting resistance as indicated by its pitting resistance equivalent number (PREN) of 52. It can be used in a broader temperature range than superduplex and hyperduplex stainless steels, offers good weldability and is more cost-effective than Nickel-based materials which make the grade a good candidate for O&G applications, refineries, and chemical industries.1,2
