Praxair Surface Technologies: A Deep Dive into Coatings and Thermal Spray

Praxair Surface Technologies (PST), now a part of Linde plc following a merger, was a leading global provider of high-performance coatings and thermal spray technologies. While the company name no longer exists as a standalone entity, its legacy and the technologies it developed remain significant within various industries. This article explores PST's history, key offerings, and the lasting impact of its innovations.

A History of Innovation:

PST's roots lie in the development and application of advanced surface technologies. The company specialized in creating coatings that significantly enhanced the performance, durability, and lifespan of components across diverse sectors. This involved a complex interplay of material science, engineering expertise, and precise application techniques. Their commitment to research and development allowed them to consistently push the boundaries of what was possible in surface modification.

Core Technologies and Services:

PST's core business revolved around several key technologies and service offerings:

• Thermal Spray: This process involved spraying molten or semi-molten materials onto a substrate to create a protective or functional coating. PST mastered various thermal spray techniques, each tailored to specific application needs and material properties. This included high-velocity oxy-fuel (HVOF), atmospheric plasma spray (APS), and others.

• High-Velocity Oxy-Fuel (HVOF): This particularly efficient thermal spray method produced extremely dense and well-bonded coatings, resulting in superior wear and corrosion resistance. PST was a pioneer in HVOF technology, applying it to a wide range of components in industries like aerospace, energy, and automotive.

• Coatings for Specific Industries: PST catered to a diverse clientele, developing specialized coatings for distinct industry applications. This involved detailed analysis of the operating conditions and specific challenges faced by each sector to engineer bespoke solutions. For example, they offered coatings that enhanced the performance of components in harsh environments, improved the efficiency of power generation equipment, or extended the lifespan of tools and machinery.

• On-Site Services: In addition to coating application, PST provided comprehensive on-site services, including surface preparation, coating inspection, and repair services. This ensured consistent quality and reduced downtime for clients.

Industries Served:

PST's coatings and thermal spray technologies served a broad range of industries, including:

• Aerospace: Coatings for aircraft engines, turbine blades, and other critical components.
• Energy: Coatings for power generation equipment, pipelines, and oilfield tools.
• Automotive: Coatings for engine components, exhaust systems, and other wear-prone parts.
• Medical: Coatings for implants and medical devices.
• Industrial: Coatings for tools, machinery, and other industrial equipment.

The Legacy of Praxair Surface Technologies:

While Praxair Surface Technologies no longer operates as an independent entity, its contributions to materials science and surface engineering are undeniable. The advanced coating technologies it developed and the expertise it fostered continue to influence various industries. The solutions created by PST have resulted in improvements in component lifespan, performance efficiency, and cost savings for countless businesses around the world. The merger with Linde has integrated this expertise into a larger organization, ensuring its continued relevance in future innovations.
