As manufacturing pursues higher efficiency, lower energy consumption, and robust reliability, coatings must remain stable under high temperature, heavy impact, and long cutting cycles. Built on an arc-deposition route, our HLM300 process for TiAlN has been benchmarked against leading international solutions to deliver stronger process reliability and longer tool life in demanding operations—milling, drilling, and turning alike.

In today's fast-paced manufacturing landscape, efficiency, precision, and durability are the driving forces behind technological innovation. The HD500, developed by Huasheng, represents a groundbreaking leap in composite coating technology. Built upon a next-generation platform that integrates high-ionization sputtering and advanced arc processes, the HD500 delivers coatings with unmatched performance, adaptability, and reliability. 

In the machining industry, turning and milling serve as the most fundamental and core processes, responsible for manufacturing critical components ranging from aerospace superalloys to automotive hardened steels. However, turning inserts experience crater wear, flank wear grooves, and high-temperature coating delamination during continuous cutting of superalloys or hardened steels, primarily due to weak adhesion and insufficient thermal stability of conventional coatings. Milling inserts frequently exhibit micro-chipping, thermal crack propagation, and built-up edges caused by material adhesion during interrupted cutting of titanium alloys or cast iron, fundamentally resulting from inadequate coating toughness and poor lubricity. These failure modes directly degrade machining accuracy and escalate production costs.

In the healthcare sector, material properties of medical devices play a critical role in treatment efficacy, with surface engineering being pivotal to device performance. Conventional metal devices (e.g., vascular stents, orthopedic implants, surgical instruments) face three major clinical challenges:

Wear in internal combustion engines is an inevitable phenomenon during operation, serving as a critical factor affecting engine lifespan, performance, and reliability. Fundamentally, wear involves the gradual loss of surface materials on friction pairs through oxidation and corrosion. Coatings play an extensive and vital role in engine components.

With the continuous advancement of the semiconductor manufacturing industry, where process technologies have progressed to 3nm and below, the requirements for semiconductor components have become increasingly stringent.  

Abstract: Multi-layer AlCrN / TiSiN composite coating film with functional layer biases of 40V,80V,120V and 150V are prepared by AIP+HiPiMS technology.Surface droplets are observed by SEM,coating hardness,coating adhesion and stress are measured,and cutting tests are conducted to explore the impact of functional layer bias changes on coating performance.It is found that as the bias voltage of the functional layer increases,the number of droplets decrease first and then increase,with the hardness and adhesion increase and then decrease.The hardness and adhesion reach their maximum at 120V,reaching 34.6GPa and 117.5N respectively.The internal stress increases with the increase of substrate bias of the functional layer.The cutting test results show that the longest service life is 8 hours with the 120V functional layer bias．
