Praxair Surface Technologies: A Deep Dive into Surface Solutions

Praxair Surface Technologies (PST), now a part of Linde plc following a merger, was a global leader in providing advanced surface technologies and coatings. While the company name no longer exists as a standalone entity, understanding its history and contributions remains relevant for comprehending the current landscape of surface treatment and coating technologies. This article delves into PST's legacy, its key offerings, and its impact on various industries.

A Legacy of Innovation in Surface Modification:

PST's core business revolved around enhancing the performance of components and materials through advanced surface modification techniques. This involved a sophisticated range of services and technologies designed to improve durability, reduce friction, resist wear, and enhance other critical properties. The company's expertise spanned various sectors, including aerospace, automotive, energy, and medical.

Key Offerings and Technologies:

PST's portfolio was extensive, encompassing several key areas:

1. Thermal Spray Coatings: This core technology involved applying protective coatings to surfaces using high-velocity jets of molten or semi-molten materials. This resulted in improved wear resistance, corrosion protection, and thermal barrier capabilities. Applications included gas turbine components, automotive parts, and tooling.

2. Chemical Conversion Coatings: PST employed various chemical processes to create protective layers on metal surfaces. These coatings enhanced corrosion resistance, lubricity, and paintability, finding applications across many industries.

3. Physical Vapor Deposition (PVD): This advanced technique deposited thin films onto substrates under vacuum conditions. PVD coatings enhanced surface hardness, wear resistance, and aesthetic appeal, commonly used in cutting tools, decorative applications, and medical implants.

4. Plasma Spray Coatings: Similar to thermal spray, plasma spray employed ionized gases to melt and accelerate coating materials, resulting in highly durable and corrosion-resistant coatings.

5. Specialized Services: Beyond coating application, PST offered specialized services such as surface preparation, component design consultation, and quality control testing. These services ensured the optimal performance and longevity of the treated components.

Industries Served:

PST's technologies served a diverse range of industries:

• Aerospace: Coatings for gas turbine blades, airframe components, and other critical parts improved performance and extended lifespan.
• Automotive: Coatings enhanced the durability and longevity of engine components, brake systems, and other crucial parts, improving fuel efficiency and vehicle lifespan.
• Energy: Coatings protected components in power generation systems, oil and gas extraction equipment, and other energy-related infrastructure from corrosion and wear.
• Medical: Biocompatible coatings for medical implants ensured compatibility with the human body and improved the performance of surgical tools.

The Linde Merger and the Future of PST's Technologies:

The integration of PST into Linde has resulted in a significant expansion of resources and technological capabilities. While the Praxair Surface Technologies name is no longer active, the technologies and expertise developed by PST continue to be applied within Linde's broader portfolio of surface treatment and coating solutions. This suggests a continued focus on innovation and the development of advanced materials and surface modification techniques.

Conclusion:

Praxair Surface Technologies played a vital role in advancing surface treatment and coating technologies. Its innovative solutions improved performance, durability, and efficiency across a wide range of industries. Although the company no longer exists under that name, its legacy continues to influence the development and application of cutting-edge surface modification techniques within Linde's broader operations. The contributions of PST highlight the critical role of surface technologies in enhancing the performance and longevity of components in diverse sectors.
