Materials and Compatibilities
Laser Clad Coatings
A wide range of materials exists for advanced coating, but Endlas helps you select the best material for your corrosion and wear applications. Coating thicknesses for most materials range from 0.01” to >0.25” thick.
Check out the chart at the bottom for a glance at compatibility between base materials and laser clad coatings.
Materials available for laser coatings can be narrowed to the following 6 categories:
Laser Clad Iron-Based Alloys
Advanced Steels alloyed with Cr, Co, W, C, Si, Mn, V, and Mo have high RT hardness through standard heat treatment cycles. Iron-Based Alloys are more susceptible to corrosive attack and may suffer from poor ‘as clad’ surface finish. Carbide and Boride precipitates strengthen the steel matrix.
Laser Clad Nickel-Based Superalloys
Nickel-Based Superalloys are complex alloys where both precipitation and solid solution hardening develop strength over a wide range of temperatures. Oxide dispersion hardening provides solid solution precipitates and is mechanically alloyed into the precursor powder.
Laser Clad Cobalt-Based Superalloys
Cobalt is alloyed with W, Cr, Mo, Fe, Ni and C to stabilize an austenitic FCC structure. Precipitation hardening does not increase the strength in these alloys, therefore very fine solid solution precipitates, which form during solidification, provide strengthening.
Laser Clad Nanostructured Ultra Alloys
A new category of advanced materials is a result of nano-structured phases which enhance strength and other properties. Nanostructured Ultra Alloys can be laser processed without an inert environment, and are known to have hardness greater than 2000 Vickers.
Laser Clad Tungsten-Carbide in Nickel
Tungsten-Carbide in Nickel alloys utilize a ‘self-fluxing’ matrix of Ni with small additions of Cr, Si and B so the matrix fully encapsulates the WC/W2C particles. WC/W2C particles can be spherical, faceted, or both.
Laser Clad Tungsten-Carbide in Cobalt
Tungsten-Carbide alloys utilize a ‘self-fluxing’ matrix of Co with small additions of Cr and C so the matrix fully encapsulates WC/W2C particles. Just like with Tungsten-Carbide in Nickel, the WC/W2C particles can be spherical, faceted, or both.
The following chart can provide you with a glimpse of potential coatings for your equipment and/or tools. While the best coating for your products is heavily dependent on operating conditions and technical requirements, we will take the guesswork out of selecting the best coating, and improve the efficiency and lifetime of your equipment.
