The growth in the historic period can be attributed to industrial machining growth, tool wear reduction demand, aerospace material innovation, semiconductor equipment usage, coating process maturity.

The diamond coatings market size is expected to see strong growth in the next few years. It will grow to $4.59 billion in 2030 at a compound annual growth rate (CAGR) of 9.1%. The growth in the forecast period can be attributed to electric vehicle component demand, precision manufacturing expansion, medical implant adoption, energy efficient machinery focus, advanced surface engineering. Major trends in the forecast period include growing adoption in cutting tools, rising use of DLC in automotive components, expansion of medical grade coatings, increasing demand for low friction surfaces, advancements in CVD and PVD techniques.

Rapid growth in the electronics industry is expected to drive the diamond coatings market. The electronics sector, which designs and manufactures devices and components for consumer, industrial, and communication applications, is expanding due to rising demand for consumer electronics and smart devices. Diamond coatings enhance this industry by offering superior hardness, wear resistance, and thermal conductivity, enabling precise machining and protection of delicate materials. For example, in July 2024, the Semiconductor Industry Association reported that global semiconductor sales reached $49.1 billion in May 2024, a 19.3% increase from May 2023.

Technological innovations in diamond coatings are improving performance and durability of high-precision tools. Chemical vapor deposition (CVD) diamond coating, which deposits a uniform synthetic diamond layer on substrates, enhances hardness, wear resistance, and thermal conductivity. For instance, in June 2025, Oerlikon Balzers launched Baldia Varia, a CVD diamond coating optimized for machining lightweight and abrasive materials such as carbon fiber reinforced polymer, graphite, and ceramics, increasing tool life and cutting accuracy for aerospace, automotive, and electronics applications.

In December 2023, SurfacePrep, a US-based surface enhancement solutions provider, acquired Diamond Tool & Abrasives Inc. to expand its portfolio of abrasive products and enhance machining and finishing expertise across industries including aerospace, automotive, and electronics.
